ANGLE PAIR CARDS

Angles are

a = b

Angles add upto 90°

a + b = 90

Angles add upto 180 °

a + b = 180

How do we set up these equations?

Page 4: Adjacent Vertical Complementary Supplementary Linear Pair Angles that share a side 2 angles whose sum is 180° Opposite angles made by two intersecting

The sum of the angles in a triangle

is 180.

a + b + c = 180

The sum of the Remote Interior

Angles equal the

measure of theExterior Angle.

n is parallel to m

A line that intersects two or

more lines.

HOT LAVAThink of the space between the two parallel lines as a river of Hot Lava and the Transversal as a bridge to

cross safely to the other side.

We have Angle Pairs with specific names.There are 8 angles made with this Transversal.
