The Students' Aptitude Test Class -9th

The sum of the angles in a triangle is always 180 degrees. Therefore, the total measure of the three angles in triangle ABC is 180 degrees.

The given options are sets of numbers. Looking at the sets, we can see that the numbers in each set are increasing by 1, except for the last number which is increasing by 3. Therefore, the set that follows this pattern is 1, 2, 7, 8.

The correct answer is A. In the given options, A is the only option that is a valid letter in the English alphabet. B and C are also valid letters, but they are not at the top position in the alphabet. The option "ନାହିଁ" is not a valid letter in the English alphabet. Therefore, A is the correct answer for the top position in the alphabet.

The correct answer is "ସମାନ୍ତର ସରଳରେଖା" (Parallel lines). This is because the question is asking which of the given options represents parallel lines. The option "ସମାନ୍ତର ସରଳରେଖା" translates to "parallel lines" in English, which is the correct answer.

The given options are different types of triangles in the Odia language. "ବିଷମବାହୁ ତ୍ରିଭୁଜ" translates to "scalene triangle" in English, which is a type of triangle where all three sides have different lengths. Therefore, the correct answer is "ବିଷମବାହୁ ତ୍ରିଭୁଜ" or "scalene triangle".

The question is asking for the type of angle. The options given are "ସମକୋଣ" (acute angle), "ସରଳକୋଣ" (straight angle), "ସ୍ଥୂଳକୋଣ" (obtuse angle), and "ସୂକ୍ଷ୍ମକୋଣ" (right angle). The correct answer is "ସ୍ଥୂଳକୋଣ" which means obtuse angle.

The question is asking about the type of triangle. The options provided are "samabahu" (equilateral), "bishamabahu" (scalene), "samadwibahu" (isosceles), and "sthulakoni" (right-angled). The correct answer is "samabahu" (equilateral) because an equilateral triangle has all three sides and angles equal.

The given options are in Odia language and represent different types of triangles. "ସମଦ୍ଵିବାହୁ ତ୍ରିଭୁଜ" translates to "Isosceles triangle" in English. Therefore, the correct answer is "Isosceles triangle".

The question is asking for the type of angle. The options given are "sthulakona" (obtuse angle), "samakona" (right angle), "sukshmakona" (acute angle), and "saralakona" (straight angle). The correct answer is "samakona" which means right angle.

The correct answer is "ସମଦ୍ଵିବାହୁ". This is because "ସମଦ୍ଵିବାହୁ" means "equilateral" in English, which refers to a triangle with all three sides of equal length.

In the given question, it is asked which angle can be the largest in a given triangle. The correct answer is 1, which means that angle 1 can be the largest angle in the triangle.

The given options are in Odia language and they represent different types of triangles. "ସମକୋଣୀ" translates to "equilateral" in English, which means all three sides of the triangle are equal in length. Therefore, the correct answer is "ସମକୋଣୀ" or "equilateral" triangle.

The question is asking for the value of x in the Odia language. The correct answer is 132, which is the only option given in numerical form.

The question asks about the type of angle shown in the picture. The correct answer is "ଅନୁରୂପ କୋଣ" which translates to "similar angle" in English. This suggests that the angle in the picture is similar to another angle, meaning that they have the same measure or are congruent.

The given options consist of three triangles with different orientations and arrangements of the letters "କୋ" and "ବା". By analyzing each option, we can see that the correct answer is "ବା-କୋ-ବା" because it is the only option where all three triangles have the same orientation and arrangement of letters.

The correct answer is "ସୂକ୍ଷ୍ମକୋଣ" which translates to "acute angle" in English. An acute angle is an angle that measures less than 90 degrees. In the given question, the options provided are different types of angles, and "ସୂକ୍ଷ୍ମକୋଣ" is the correct term for an acute angle.

The given question asks for the type of angle formed by the numbers 3 and 6, and 4 and 5 in the picture. From the options provided, "ଏକାନ୍ତର କୋଣ" (eekantar kona) translates to "adjacent angle" in English. Therefore, the correct answer is "ଏକାନ୍ତର କୋଣ" (adjacent angle).

The given options in the question are different types of triangles in the Odia language. The correct answer "ସମବାହୁ" translates to "equilateral" in English. An equilateral triangle is a type of triangle where all three sides are of equal length. Therefore, the correct answer is "equilateral" triangle.

The correct answer is "ପରସ୍ପର ଛେଦୀ" which means "intersecting". This is because the given options "ପରସ୍ପର ଛେଦୀ", "ଅଣଛେଦି", "ସମାନ୍ତର", and "ତୀର୍ଯ୍ୟକ" correspond to the terms "intersecting", "non-intersecting", "parallel", and "perpendicular" respectively. Therefore, the correct answer is "ପରସ୍ପର ଛେଦୀ" which means "intersecting".

The given question presents a sequence of line segments: PR, PQ, QR, and PQR. The correct answer, PR, is the first line segment in the sequence. Each line segment is formed by connecting two points, and the sequence follows a pattern where the second point of each line segment becomes the first point of the next line segment. Therefore, the correct answer is PR, as it is the first line segment in the sequence.

The question is asking which number is in the middle of the given triangle. The numbers 1, 2, and 3 are listed, and the number 3 is in the middle.

The given answer, "ସମକୋଣୀ ସମଦ୍ଵିବାହୁ", means "equiangular isosceles triangle" in English. This type of triangle has two equal angles and two equal sides.

The correct answer is "ସନ୍ନିହିତ କୋଣ" which translates to "adjacent angle" in English. In geometry, adjacent angles are two angles that share a common vertex and a common side, but do not overlap. In this question, "v" and "y" are mentioned as angles, and the term "ସନ୍ନିହିତ" indicates that they are adjacent angles.
