What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

What is a midpoint?

Back

A midpoint is the point that divides a line segment into two equal parts.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect to form a right angle (90 degrees).

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

What is the distance formula in coordinate geometry?

Back

The distance formula is used to determine the distance between two points (x1, y1) and (x2, y2) and is given by: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.
