What are congruent angles?

Back

Congruent angles are angles that have the same measure. In a triangle, if two angles are congruent, the sides opposite those angles are also equal in length.

Front

What is a reflection in geometry?

Back

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

What is the conclusion in a conditional statement?

Back

In a conditional statement of the form 'If P, then Q', the conclusion is Q. For example, in 'If I have a Siberian Husky, then I have a dog', the conclusion is 'I have a dog'.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees. For example, if one angle measures 120 degrees, the other must measure 60 degrees.

What is the transformation that moves a shape without changing its orientation?

Back

Translation is the transformation that moves a shape in a straight line from one position to another without rotating or flipping it.

Front

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

Back

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

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a fixed point, while reflection flips it over a line. In rotation, the orientation changes, but in reflection, it remains the same.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices. The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the Pythagorean theorem?

Back

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.
