Kendall Hunt Geometry Unit 2 Review

Front

What is the measure of angle P if angle Q measures 70 degrees in a triangle?

Back

Angle P measures 40 degrees.

Front

Why does the image of point U coincide with point J when triangle STU is reflected across line ST?

Back

Line ST is the perpendicular bisector of the segment connecting U and J, making U and J equidistant from line ST.

Front

What sequence of rigid motions can be used to map triangle GHJ onto triangle STU?

Back

Translate GHJ by the directed line segment GS, rotate around point S by angle H'ST, and reflect over line ST.

Front

Which triangle congruence theorem is applicable to prove triangle ADE is congruent to triangle CBE?

Back

Angle-Side-Angle (ASA) theorem.

Front

If triangles ACD and BCD are isosceles with angle BAC measuring 18 degrees and angle BDC measuring 48 degrees, what is the measure of angle ABD?

Back

Angle ABD measures 138 degrees.

Front

What is the definition of a perpendicular bisector?

Back

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

Front

What are rigid motions in geometry?

Back

Rigid motions are transformations that preserve distance and angle measures, including translations, rotations, and reflections.

Front

What is the Angle-Side-Angle (ASA) congruence theorem?

Back

The ASA theorem states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Front

How do you find the measure of an unknown angle in a triangle?

Back

Use the fact that the sum of the interior angles in a triangle is always 180 degrees.

Front

What is the relationship between the angles in an isosceles triangle?

Back

In an isosceles triangle, the angles opposite the equal sides are also equal.
