Question 1

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

Accepted Answer

180°

Answer

The interior angles of any triangle always sum to 180°.

Question 2

Two lines that never intersect and are always the same distance apart are called:

Accepted Answer

Parallel lines

Answer

Parallel lines lie in the same plane, never intersect, and maintain a constant distance from each other.

Question 3

If two angles are supplementary, their measures add up to:

Accepted Answer

180°

Answer

Supplementary angles are two angles whose measures sum to 180°, forming a straight line when adjacent.

Question 4

A right angle measures exactly:

Accepted Answer

90°

Answer

A right angle is exactly 90° and is indicated by a small square symbol in geometric diagrams.

Question 5

The Pythagorean theorem states that for a right triangle with legs a and b and hypotenuse c:

Accepted Answer

a² + b² = c²

Answer

The Pythagorean theorem states a² + b² = c², relating the squares of a right triangle's three sides.
