If you visit Washington D.C., you might see this five-sided figure.

What is…….. the Pentagon

This is the symmetry this shape has.

What is…….. rotational symmetry (180° rotation) · ·

This polygon has exactly one pair of parallel sides.

What is…….. a trapezoid

This polygon differs from a square only in having different sizes of angle sets.

What is…….. a rhombus

You would get this type of line if you draw a perpendicular line through an isosceles triangle.

What is…….. symmetry

This is the point where the sides of an angle meet.

What is…….. a vertex

This is an angle that measures between 90 and 180. °

What is…….. an obtuse angle

This is an accurate measurement you will get by measuring the angle below with a protractor.

What is…….. 75 °

This is what you would draw if you wanted to create a 155 angle with a protractor. °

What is……..

These are the estimated measures of the numbered angles in the diagram below. 1 2 4 3 3

What is…….. m 1 = 120° m 2 = 135° m 3 = 45° m 4 = 60° 1 2 3 4

This is a triangle with one 90° interior angle.

What is…….. a right triangle

These are the measures of the missing angles in the diagram below. x 25° y

What is…….. m x = 25° m y = 65° x 25° y

This describes why/why not a regular octagon can tile a surface.

What is…….. the interior angle of a regular octagon is 135°. 135 is not a factor of 360 (can not add up to 360). It can not completely surround a point without overlapping.

This is the measure of the numbered exterior angle 1 in the diagram below. 138° 1

What is…….. 42° 180° – 138° = 42°

This is the interior angle sum for a regular pentagon. (And this is my work/explanation.)

540 What is…….. ° (n-2) • 180 = angle sum (5-2) • 180 = 540 or, 3 triangles • 180 = 540 °

This triangle has all angle measures that are less than 90°

What is…….. an acute triangle

This triangle has no sides of equal length.

What is…….. a scalene triangle

What shape you can make with three sides with the lengths 12, 7, and 19.

a straight line not a triangle What is…….. a straight line or not a triangle

This is what is true about a triangle with only two angles the same size; this is the name of the triangle.

exactly two sides are the same length. This is an isosceles triangle. What is…….. exactly two sides are the same length. This is an isosceles triangle.

This is the measure of the missing angle. 48° x

What is…….. 66° (180 – 48 = 132. 132 ÷ 2 = 66)

This is what is true about the side lengths of a polygon in order to build a rectangle that is not a square.

What is…….. There are two pairs of sides that are the same, but all four sides are NOT the same.

This describes whether or not you can make two different quadrilaterals with the same 4 side lengths.

What is…….. you can make a different quadrilateral with the same side lengths if you change the angles, or change the order of the sides (if they are not all the same length.)

This explains whether or not the sides lengths 4, 7, 9, and 14 can make a quadrilateral.

What is…….. the side lengths 4, 7, 9, and 14 can make a quadrilateral because the three smallest sides add up to more than the fourth, largest side.

This is the sum of the exterior angles of a quadrilateral, and how we know this.

What is…….. 360°. We know this because in order for the exterior angles to go completely around the quadrilateral, they would have to make a full rotation, 360°

This is a drawing of a quadrilateral with one diagonal that is a line of symmetry.

(the diagonal in a square) What is…….. (the diagonal in a square)
