7th Grade Geometry Quiz

The interior angles of every triangle always add up to 180 degrees, no matter the type of triangle.

 Area of a rectangle = length × width. So, 8 × 5 = 40 cm².

A right angle always measures exactly 90 degrees.

Perimeter of a square = 4 × side length. So, 4 × 6 = 24 cm.

Supplementary angles add up to 180 degrees, which forms a straight line.

 An equilateral triangle has three equal sides and three equal angles.

Area of a triangle = (base × height) ÷ 2. So, (10 × 6) ÷ 2 = 30 cm².

An acute angle is any angle less than 90 degrees.

 A hexagon is a polygon with six sides.

 Volume = length × width × height. So, 4 × 3 × 5 = 60 cm³.
