• 1.

### Identify this polygon.

• A.

Triangle

• B.

Convex

• C.

Concave

• D.

Hexagon

C. Concave
Explanation
A concave polygon is a polygon with at least one interior angle greater than 180 degrees. In other words, it has at least one "caved-in" or "dented" portion. In contrast, a convex polygon has all interior angles less than 180 degrees. Since the question asks to identify the polygon, and the answer is "Concave," we can conclude that the polygon being referred to has at least one interior angle greater than 180 degrees, making it a concave polygon.

### The 6 sided polygon is called _________________________________

Hexagon, hexagon
Explanation
A 6 sided polygon is called a hexagon. The term "hexagon" is derived from the Greek words "hexa," meaning six, and "gonia," meaning angle. It is a polygon with six sides and six angles. The answer provided, "Hexagon, hexagon," simply repeats the correct term twice for emphasis.

Rate this question:

• 3.

### Identify the type of polygon.

• A.

Regular

• B.

Irregular

• C.

Convex

• D.

Concave

B. Irregular
Explanation
The given question asks to identify the type of polygon. The options provided are "Regular," "Irregular," "Convex," and "Concave." The correct answer is "Irregular." A polygon is considered irregular if it does not have equal side lengths or equal angles. In contrast, a regular polygon has all sides and angles equal. Therefore, the correct answer is "Irregular" as it indicates a polygon that does not meet the criteria of a regular polygon.

### What is the term for a polygon with eight sides?

• A.

Hexagon

• B.

Dodecagon

• C.

Decagon

• D.

Octagon

D. Octagon
Explanation
An octagon is a polygon with eight sides. The term is derived from the Latin word "octo" meaning eight. Octagons commonly appear in various contexts, such as stop signs. They have eight angles and eight vertices, and the sum of their interior angles is 1080 degrees. The study of polygons and their properties is fundamental to geometry and mathematics.

Rate this question:

• 5.

### Which type of polygon is this?

• A.

Regular

• B.

Irregular

• C.

Simple polygon

• D.

None of the above

A. Regular
Explanation
This polygon is classified as "Regular" because all of its sides are equal in length and all of its angles are equal.

Rate this question:

• 6.

### Identify the type of angle.

• A.

Supplementary

• B.

Complementary

• C.

Vertically opposite

• D.

Angles on a line

B. Complementary
Explanation
Complementary angles are two angles that add up to 90 degrees. In this case, the given answer "Complementary" indicates that the type of angle being referred to is complementary.

Rate this question:

• 7.

### Find the angles

• A.

30^, 60^

• B.

40^, 50^

• C.

45^,45^

• D.

20^, 70^

A. 30^, 60^
Explanation
The given angles 30^ and 60^ form a pair of complementary angles, which means that when added together, they equal 90 degrees. In a right triangle, one of the angles is always 90 degrees, so the other two angles must add up to 90 degrees as well. Therefore, the angles 30^ and 60^ can be the angles of a right triangle.

Rate this question:

• 8.

### A __________ is a point where two sides meet.

corner, Corner, vertex
Explanation
A vertex or corner is a point where two sides or edges meet in geometry. It is a fundamental concept in mathematics and can refer to the meeting point of lines, edges of polygons, or nodes in a graph.

Rate this question:

• 9.

### ___________ triangle has no line of symmetry.

scalene, Scalene
Explanation
A scalene triangle is a triangle in which all three sides have different lengths, and a Scalene triangle has no line of symmetry. This means that there is no line that can be drawn through the triangle that divides it into two equal halves. Therefore, the correct answer is "scalene, Scalene".

Rate this question:

• 10.

### Two angles are called supplementary when their measures sum up to _______ degrees.

• A.

180

• B.

90

• C.

270

• D.

360

A. 180
Explanation
Two angles are called supplementary when their measures sum up to 180 degrees. This means that if we add the measure of one angle to the measure of another angle and the result is 180 degrees, then the angles are supplementary. For example, if one angle measures 90 degrees, then the other angle must measure 90 degrees as well in order for them to be supplementary.
