What must the angles in a triangle add up to?

If a triangle has a 32° angle and a 67° angle, what is the measurement of the third angle?

If two angles of a triangle add up to 110° , what is the measure of the third angle?

If a triangle has a 22° angle and a 46° angle, what can be established about the third angle measure and the type of triangle?

• The third angle measure is 68°, and the triangle is an obtuse triangle.

• The third angle measure is 128°, and the triangle is an obtuse triangle.

• The third angle measure is 112°, and the triangle is an obtuse triangle.

• he third angle measure is 112°, and the triangle is an acute triangle.

Can a triangle have two right angles, and why or why not?

• Yes, becasue 90 + 90 = 180

• No, because a triangle must have an obtuse angle.

• No, because there needs to be a third angle.

• Yes, because it would be a right triangle.
