What is a Convex Heptagon?

Back

A convex heptagon is a seven-sided polygon where all interior angles are less than 180 degrees, and no vertices point inward.

Front

What is a Concave Heptagon?

Back

A concave heptagon is a seven-sided polygon that has at least one interior angle greater than 180 degrees, causing at least one vertex to point inward.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. Their measures add up to 180 degrees.

Front

What are Adjacent Angles?

Back

Adjacent angles are two angles that share a common vertex and a common side but do not overlap.

Front

What is an Equiangular Triangle?

Back

An equiangular triangle is a triangle in which all three angles are equal, each measuring 60 degrees.

Front

What is an Acute Triangle?

Back

An acute triangle is a triangle where all three interior angles are less than 90 degrees.

Front

What is an Obtuse Triangle?

Back

An obtuse triangle is a triangle that has one interior angle greater than 90 degrees.

Front

What is a Right Triangle?

Back

A right triangle is a triangle that has one interior angle equal to 90 degrees.
