What is a polygon?
A geometric figure closed by three or more segments.
100
How is an exterior angle formed?
An exterior angle is formed by extending a side of the polygon.
100
What is the SSS Theorem?
SSS stands for "side, side, side". If three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.
100
If the perimeter of a square is 80. What is the area of that square?
400.
100
How many sides does a decagon have?
10
200
If the measure of each interior angle of a polygon is 150 degrees, how many sides does it have? A. 10 B. 12 C. 15 D. Not enough information
D. Not enough information
200
Complete the Exterior Angle Theorem. If A polygon has x sides, the sum of the measures of it's exterior angles is ______.
Equal to the sum of the two non-adjacent angles.
200
What is the AAS Theorem?
AAS stands for "angle, angle, side". If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
200
How do you find the area of a rhombus?
To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2) or A=1/2ab
200
True or false? The median of a triangle is always in the middle of one of the angles.
False. The median of a triangle is always in the middle of the opposite side.
300
If the sum of measures of the interior angles of a polygon is 2700 degrees, how many sides does it have? A. 9 B. 15 C. 17 D. Not enough information.
C. 17
300
What is the measure of each exterior angle of a stop sign?
45 degrees.
300
Is AAA or angle, angle, angle enough information to decide if two triangles are congruent? Why or why not?
No, because the triangles can have the same angles but different sides. Without knowing at least one side, we can't be sure if two triangles are congruent.
300
What do the adjacent sides of a parallelogram add up to?
Adjacent sides of a parallelogram are supplementary. Their measures add up to 180 degrees.
300
What is the name given to plygons whose sides all have the same length?
Regular.
400
What is a concave polygon?
A concave polygon that has one or more interior angle(s) measuring more than 180 degrees.
400
What is the sum of the exterior angles of a polygon with 36 sides?
360 degrees.
400
What is HL?
HL stands for hypotenuse leg and only applies to right-angled triangles. If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
400
What is the formula to find the area a trapezoid?
A=1/2h (B+b)
400
Find the measure of the interior angles of a regular polygon with 6 sides.
Interior = 120 degrees each
500
If hexagon with four interior angles measuring; 87 degrees, 108 degrees, 140 degrees, and 100 degrees. What is the measure of the remaining angle?
105 degrees

A. 2+3=5 1<5 Yes B. 5+8=13 2<13 Yes
500
How many ways are there to find if two or more triangles are congruent and what are they?
There are 5 different ways. SSS, SAS, ASA, AAS, and HL.
500
What is a trapezium and how many types are there?
Trapeziums are quadrilaterals with one pair of opposite sides which are parallel and of unequal length. The other sides are not parallel. There are 3 types of trapezium.

D. (n-2)180
