Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle. It is parallel to the third side and its length is half the length of that side.

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation. A scale factor of less than 1 reduces the size, while a scale factor greater than 1 enlarges it.

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure, regardless of their position or orientation.

Front

What is a congruence statement in geometry?

Back

A congruence statement is a way to express that two geometric figures are congruent, indicating that they have the same shape and size. It typically lists corresponding parts in the same order.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

Front

What is an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex of a triangle to the line containing the opposite side. It represents the height of the triangle.

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but maintains its shape, using a scale factor to determine the degree of enlargement or reduction.

Front

What is the difference between a median and a midsegment in a triangle?

Back

A median connects a vertex of a triangle to the midpoint of the opposite side, while a midsegment connects the midpoints of two sides.
