What is the definition of a perpendicular bisector?

Back

A perpendicular bisector is a line that divides a line segment into two equal parts at a 90-degree angle.

Front

How do you find the coordinates of a translated point?

Back

To find the coordinates of a translated point, add the translation values to the original coordinates. For example, if the translation is (x, y) to (x - 1, y + 2), subtract 1 from the x-coordinate and add 2 to the y-coordinate.

What is the perimeter of an equilateral triangle with side length 24?

Back

The perimeter of an equilateral triangle is calculated as P = 3 * side length. Therefore, P = 3 * 24 = 72.

Front

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.

Front

How do you find the other endpoint of a line segment given one endpoint and the midpoint?

Back

To find the other endpoint, use the midpoint formula: Midpoint = ((x1 + x2)/2, (y1 + y2)/2). Rearranging gives x2 = 2*Midpoint_x - x1 and y2 = 2*Midpoint_y - y1.

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 HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for triangle congruence applicable to right triangles where the hypotenuse and one leg are equal.

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.

Front

What is a translation in geometry?

Back

A translation is a geometric transformation that moves every point of a shape a constant distance in a specified direction.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.
