UNIT 7 ANGLES, TRIANGLES AND PRISMS

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Complementary angles are two angles that add up to 90 degrees.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

Can a triangle have angles measuring 47°, 84°, and 56°?

Back

No, because the sum of the angles is 187°, which exceeds 180°.

Front

What is the surface area of a triangular prism?

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is a prism?

Back

A prism is a solid shape with two identical ends and flat sides.
