### A triangle with one right side.

• A.

Acute triangle

• B.

Equiangular triangle

• C.

Obtuse triangle

• D.

Right triangle

D. Right triangle
Explanation
A right triangle is a triangle that has one angle measuring 90 degrees, which is a right angle. In this case, the given triangle has one right side, indicating that it has a right angle. Therefore, the correct answer is "Right triangle."

### A simple closed two-dimensional shape made of line segments.

• A.

Trapezoid

• B.

Rhombus

• C.

Polygon

• D.

Kite

C. Polygon
Explanation
A polygon is a simple closed two-dimensional shape made of line segments. It can have any number of sides, as long as the sides do not cross each other. A trapezoid is a specific type of quadrilateral with one pair of parallel sides. A rhombus is a quadrilateral with all sides of equal length. A kite is a quadrilateral with two pairs of adjacent sides that are equal in length. Therefore, the correct answer is polygon, as it is the most general term that encompasses all the other shapes listed.

### Eight sides and eight angles.

• A.

Pentagon

• B.

Octoagon

• C.

Concave

• D.

Cone

B. Octoagon
Explanation
The given correct answer is "Octagon" because an octagon has eight sides and eight angles. An octagon is a polygon with eight straight sides and eight interior angles. It is a two-dimensional shape that is commonly used in architecture and design. The prefix "octo-" in "octagon" refers to the number eight, which accurately describes the characteristics of this shape.

### Five sided polygon.

• A.

Cyclinder

• B.

Pentagon

• C.

Diagonal

• D.

Prism

B. Pentagon
Explanation
A pentagon is a five-sided polygon. The other options listed, such as cylinder, diagonal, and prism, do not have five sides. Therefore, the correct answer is Pentagon.

### Correponding angles are congruent.

• A.

False

• B.

True

B. True
Explanation
Corresponding angles are congruent means that when two lines are crossed by a transversal, the angles that are in the same position on the lines are equal in measure. This statement is true, as corresponding angles will always be congruent.

Rate this question:

• 6.

### Same interior angles are supplementary.

• A.

True

• B.

False

A. True
Explanation
The statement "Same interior angles are supplementary" is true. Supplementary angles are angles that add up to 180 degrees. If two angles are interior angles of the same pair of parallel lines, they are called corresponding angles. Corresponding angles are congruent, meaning they have the same measure. Therefore, if two corresponding angles are congruent, their measures must add up to 180 degrees, making them supplementary.
