Geometry Unit 3 Test

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal, each measuring 60 degrees.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths and all three angles are different.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length and the angles opposite those sides are equal.

Front

What is a right triangle?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal.

Front

What is the construction 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

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 a rigid motion?

Back

A rigid motion is a transformation that preserves distance and angle measures, such as translations, rotations, and reflections.

Front

What is the relationship between two congruent triangles?

Back

If two triangles are congruent, there exists a sequence of rigid motions that can map one triangle onto the other.

Front

What does it mean to map a triangle using a reflection?

Back

Mapping a triangle using a reflection means flipping the triangle over a line (the line of reflection) to create a mirror image.
