Geometry Semester 1

Front

What are translations, rotations, and reflections?

Back

They are three different types of transformations in geometry.

Front

What is the centroid in a triangle?

Back

The centroid is the intersection of the medians of a triangle.

Front

If two triangles are similar, what can be inferred about their corresponding sides?

Back

The ratios of their corresponding sides are equal.

Front

What is the original figure prior to a transformation called?

Back

Pre-image.

Front

Solve for y: 2y + 8 = 28.

Back

y = 10.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a shape over a line, while a rotation turns a shape around a point.

Front

What are medians in a triangle?

Back

Medians are line segments that connect a vertex to the midpoint of the opposite side.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What does it mean for two shapes to be congruent?

Back

Two shapes are congruent if they have the same size and shape.
