How many degrees are in a triangle?
180
The area of a triangle
1/2*base*height
angles on a straight line add up to
180°
While at least 8 think I'm lazy, I go on and on.
infinity symbol ∞
All momentum must cease at the sight of me
octagon
90
area is defined by length times width for this shape
Rectangle
4 triangles, 3 meeting at each vertex
tetrahedron
All things being equal, I represent order, trust, stability, and being grounded.
Square
Give right of way and stop if necessary if any other traffic is in, or closely approaching, the intersection.
Triangle
The sum of the three interior angles of a triangle

Circle
Used to represent justice, mercy, and wisdom
pentagram
typically yellow or orange, I warn of dangerous or unusual conditions ahead, such as a curve, turn, dip or side road.
Diamond
True or false: Supplementary angles always add up to 180
True
My area is determined by multiplying pi times radius squared
circle
Regularly, I have 5 edges, 5 vertices and my perimeter is 5*side. My internal angles are 108°, the sum of all 5 is 540°
Pentagon
Announcing school zones, I show a black silhouette of a schoolboy and a schoolgirl.
pentagon
a triangle with one interior angle measuring more than 90°.
Obtuse triangle
