What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
The sum of the measures of two interior angles of a triangle is 261 What is the measure of the third exterior angle?
That's not possible.Two interior angles of a triangle can't add up to 261°, because all three of the interior anglesin any triangle always add up to 180°.
What type of Triangle has two 35 degree angles?
Since the triangle has two identical angles, it will be an isosceles triangle. Also the third angle equals 110°, so it is an obtuse triangle, because 110° is greater than a right angle (90°). The sum of all interior angles in a triangle is 180°, so we know two of the angles are 35° and 35°, so the third angle is 180° - 35°- 35° = 110°
What is the Exterior Angle Theorem for a Triangle?
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
In triangle DCF if angle ADF is the exterior angle the remote interior angles are?
angle dcf and angle dfc
