SELECT ALL interior angles of the shape.

Answer explanation

Interior angles are formed by two sides of a polygon.

SELECT ALL exterior angles of the shape.

Answer explanation

Exterior angles are formed by on side of a shape, and a extension of an adjacent side.

Answer explanation

Remote interior angles are angles that are interior angles to a polygon that are not adjacent to the exterior angle in question.

• vertical angles

• right angles

• vertex angles

• remote interior angles

The Triangle Sum Theorem says that the ​ (a)   angles of a triangle add up to ​ (b)   degrees.

• interior
• 180
• exterior
• 90
• 360
• remote interior

The Polygon Angle Sum Theorem says that the sum of the ​ (a)   angles of a polygon is equal to ​​ (b)   degrees.

• interior
• 180(n - 2)
• exterior
• 360(n - 2)
• 180(n - 1)
• 180n
• 360(n - 1)

A ___________ polygon has all congruent angle measures and all congruent side lengths.

Reorder the following from least to greatest number of sides.

• Triangle

• Hexagon

• Decagon

• Octagon

• Pentagon

Plot the following three points:

The Origin

(2, 8)

(4, 0)

Note that these three points will make an isosceles triangle if connected.

Answer explanation

Note that the two points at the bottom would connect to create the base, and each of those points connected to the point at the top would create the two legs.
