What is the sum of the interior angles of a triangle?
Answer: 180°
The interior angles of any triangle always sum to 180°.
Two lines that never intersect and are always the same distance apart are called:
Answer: Parallel lines
Parallel lines lie in the same plane, never intersect, and maintain a constant distance from each other.
If two angles are supplementary, their measures add up to:
Answer: 180°
Supplementary angles are two angles whose measures sum to 180°, forming a straight line when adjacent.
A right angle measures exactly:
Answer: 90°
A right angle is exactly 90° and is indicated by a small square symbol in geometric diagrams.
The Pythagorean theorem states that for a right triangle with legs a and b and hypotenuse c:
Answer: a² + b² = c²
The Pythagorean theorem states a² + b² = c², relating the squares of a right triangle's three sides.
An isosceles triangle has:
Answer: Exactly two sides equal
An isosceles triangle has exactly two congruent (equal-length) sides and the base angles opposite those sides are also equal.
