Angle Properties

How many degrees are there in a triangle?

• 180

• 360

• 90

• Every triangle is different

Calculate the value of x.

• $95\degree$

• $55\degree$

• $125\degree$

• $305\degree$

Angles a and b sum to 180 degrees.

These are examples of...

• Supplementary angles

• Co-interior angles

• Vertically Opposite angles

• Alternate angles

Solve for x.

• $62\degree$

• $118\degree$

• $28\degree$

• $45\degree$

Angles a and b are equal. What kind of angles are they?

• External

• Vertically Opposite

• Supplementary

• Corresponding

Angles a, b and c sum to how many degrees?

• $140\degree$

• $220\degree$

• $360\degree$

• $320\degree$

Calculate the value of angle x.

• $112\degree$

• $90\degree$

• $22\degree$

• $68\degree$

Consider angle 4.

Angle 4 is equal to...

• Angle 2

• Angle 1 + Angle 3

• Angle 3 - 180 degrees

• Angle 1 + Angle 2

Solve for both C and D.

• $C=68\degree\ and\ D=68\degree$

• $C=35\degree\ and\ D=68\degree$

• $C=68\degree\ and\ D=35\degree$

• $C=112\degree\ and\ D=68\degree$

Solve for y.

• $87\degree$

• $29\degree$

• $67\degree$

• $43.5\degree$
