24 - 25 Geometry Semester 1 Finals Review

Front

What is a congruent triangle?

Back

Triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

How can you determine if two triangles are congruent?

Back

By using criteria such as SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), or HL (Hypotenuse-Leg for right triangles).

Front

What is an isosceles trapezoid?

Back

A trapezoid with at least one pair of parallel sides and the non-parallel sides (legs) are equal in length.

Front

How do you find the measure of an angle in an isosceles trapezoid?

Back

The angles adjacent to each base are supplementary, meaning they add up to 180 degrees.

Front

What is the formula for finding the value of y in a linear equation?

Back

To solve for y, isolate y on one side of the equation using algebraic operations.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

How do you find the slope of a line given its equation in slope-intercept form?

Back

The slope is the coefficient of x in the equation y = mx + b, where m is the slope.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The slopes of two perpendicular lines are negative reciprocals of each other.

Front

What is the value of x in a triangle if the angles are 60 degrees, 60 degrees, and x degrees?

Back

x = 60 degrees, since the sum of angles in a triangle is 180 degrees.

Front

How do you solve for an unknown variable in an equation?

Back

Use inverse operations to isolate the variable on one side of the equation.
