Semester 1 Geometry Final 2024

Front

What is the result of rotating a triangle 90° counterclockwise around the origin?

Back

The triangle's position changes, and its coordinates are transformed according to the rotation rules. For example, a point (x, y) becomes (-y, x).

Front

What is the value of x in the equation if x + 20 = 100?

Back

x = 80

Front

How many lines of symmetry does a regular hexagon have?

Back

A regular hexagon has 6 lines of symmetry.

Front

What does a translation do to a figure on the coordinate plane?

Back

A translation slides the figure to a new position without changing its shape or orientation.

Front

If point C is between points A and B, what is the correct Segment Addition statement?

Back

AC + CB = AB

Front

Define 'line of symmetry'.

Back

A line of symmetry is a line that divides a figure into two mirror-image halves.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the difference between rotation and reflection in geometry?

Back

Rotation turns a figure around a point, while reflection flips a figure over a line.

Front

How do you find the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width).

Front

What is a congruent figure?

Back

Congruent figures are shapes that are the same size and shape, meaning they can be superimposed on each other.
