Questions and Answers
- 1.
This type of triangle has one 90 degree angle.
- A.
Acute
- B.
Right
- C.
Obtuse
Correct Answer
B. RightExplanation
A triangle with one 90 degree angle is called a right triangle. In a right triangle, one of the angles measures exactly 90 degrees, making it the largest angle in the triangle. The other two angles in a right triangle are acute angles, meaning they are less than 90 degrees. Therefore, the correct answer is right.Rate this question:

A ________ triangle is one where all 3 angles measure less than 90 degrees.
- A.
Acute
- B.
Right
- C.
Obtuse
Correct Answer
A. AcuteExplanation
An acute triangle is a triangle where all three angles measure less than 90 degrees. This means that none of the angles in the triangle are right angles (90 degrees) or obtuse angles (greater than 90 degrees).Rate this question:

A triangle where all sides are congruent is called
- A.
Scalene
- B.
Isosceles
- C.
Equilateral
Correct Answer
C. EquilateralExplanation
An equilateral triangle is a triangle where all sides are congruent. This means that all three sides of the triangle have the same length. In contrast, a scalene triangle has no congruent sides, and an isosceles triangle has two congruent sides. Therefore, the correct answer is equilateral.Rate this question:

An isosceles triangle has
- A.
No congruent sides
- B.
2 congruent sides
- C.
3 congruent sides
Correct Answer
B. 2 congruent sidesExplanation
An isosceles triangle is a triangle with two sides of equal length. The term "isosceles" means "equal legs," referring to the two congruent sides of the triangle. The third side, called the base, may have a different length.Rate this question:

All 3 interior angles of a triangle add up to
- A.
90 degrees
- B.
180 degrees
- C.
360 degrees
Correct Answer
B. 180 degreesExplanation
The correct answer is 180 degrees because the sum of the interior angles of any triangle is always equal to 180 degrees. This is a fundamental property of triangles in Euclidean geometry. No matter the size or shape of the triangle, the sum of its three interior angles will always be 180 degrees.Rate this question:

- A.
Obtuse scalene
Correct Answer
