Fall 24 Final Exam Review Part 2

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 does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, which can be proven through various criteria such as SSS, SAS, ASA, AAS, or HL.

Front

What is the Midpoint Theorem?

Back

The Midpoint Theorem states that the segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart and have the same slope.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more other lines at distinct points.

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 Alternate Interior Angles Theorem?

Back

The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

What is the Same Side Interior Angles Theorem?

Back

The Same Side Interior Angles Theorem states that if two parallel lines are cut by a transversal, then each pair of same side interior angles is supplementary.

Front

What is the Transitive Property of Equality?

Back

The Transitive Property of Equality states that if a = b and b = c, then a = c.

Front

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

Back

The sum of the interior angles in a triangle is always 180 degrees. To find an unknown angle, subtract the sum of the known angles from 180.
