Geometry Semester 1 Exam Review 2024-2025

Front

What is an angle bisector?

Back

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

Front

How do you construct an angle bisector using a compass?

Back

Fix the compass on the vertex of the angle and draw arcs that intersect both sides of the angle. Then, without changing the compass width, draw arcs from the intersection points to find the bisector.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the HL (Hypotenuse-Leg) theorem?

Back

The HL theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two triangles are congruent.

Front

What does SSA stand for in triangle congruence?

Back

SSA stands for Side-Side-Angle, which does not guarantee triangle congruence.

Front

What is the formula for the volume of a cylinder?

Back

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a fixed point, while reflection flips a shape over a line.

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 is the significance of the x-axis in transformations?

Back

The x-axis is often used as a line of reflection in transformations, where points are mirrored across this axis.
