Back

A right triangle is a triangle that has one angle measuring 90 degrees.

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 does it mean to reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, you change the sign of the y-coordinate, resulting in the point (x, -y).

Front

What is the rule for translating a point 2 units to the right and 1 unit down?

Back

The rule for this translation is (x + 2, y - 1).

Front

What are the properties of a parallelogram?

Back

In a parallelogram, opposite sides are equal in length, opposite angles are equal, and the diagonals bisect each other.

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 SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the definition of a rectangle?

Back

A rectangle is a parallelogram with four right angles.

Front

What does it mean for diagonals to be congruent in a parallelogram?

Back

If the diagonals of a parallelogram are congruent, it means they are of equal length, which indicates that the parallelogram is a rectangle.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.
