24-25 Midterm Review

Front

What is line symmetry?

Back

Line symmetry occurs when a figure can be divided into two identical halves that are mirror images of each other.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a figure can be rotated around a central point and still look the same at certain angles.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If ∆AIG ≅ ∆QOW, what can we say about their corresponding sides?

Back

The corresponding sides of the triangles are equal in length.

Front

What is the significance of the congruency statement in geometry?

Back

A congruency statement indicates which parts of two geometric figures are equal, helping to solve for unknown lengths or angles.

Front

What is the measure of angle F if it is congruent to angle G?

Back

The measure of angle F is equal to the measure of angle G.

Front

How do you determine if a figure has both line and rotational symmetry?

Back

A figure has both types of symmetry if it can be folded along a line to create mirror images and can be rotated around a point to match its original position.

Front

What is the relationship between angles in congruent triangles?

Back

In congruent triangles, corresponding angles are equal.

Front

What is the formula for finding the sum of interior angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

If angle A measures 60 degrees, what is the measure of angle B in a triangle where angle C is 90 degrees?

Back

Angle B measures 30 degrees.
