Geometry - 1st Semester Review

Front

What is a segment bisector?

Back

A segment bisector is a line, ray, or segment that divides another segment into two equal parts.

Front

If OQ = 32 and PO = 4x, what is the value of x?

Back

x = 8

Front

What is the formula for finding the length of a segment when given midpoints?

Back

If D is the midpoint of EF, then EF = ED + DF.

Front

If ED = 4x + 6 and DF = 7x - 9, how do you find EF?

Back

Set ED equal to DF and solve for x, then substitute back to find EF.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence.

Front

What is the value of x if the equation is set up as 4x + 6 = 7x - 9?

Back

x = 16

Front

How do you determine if two triangles are congruent?

Back

You can use criteria such as SSS, SAS, ASA, or AAS to determine triangle congruence.

Front

What is the definition of a midpoint?

Back

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

Front

If the angles of a triangle are 50°, 60°, and 70°, what can you say about the triangle?

Back

The triangle is valid and the angles sum up to 180°.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles of a triangle is always 180°.
