The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
How do you find an angle in quadrangle without a protractor?
Measure the two sides adjacent to the angle and the diagonal at the far ends of these sides. Then use the cosine rule to calculate the angle.
Is it true or false the measure of an exterior angle and the adjacent interior angle sum to 180 degress?
True
How do you use the exterior angles of a triangle to find interior angle measurements?
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
What is an adjacent corresponding angle?
an adjacent corresponding angle is an angle which is adjacent to a particular angle as well as corresponding.
What is the measure of an exterior angle adjacent to the vertex angle?
It is: 180-vertex angle = exterior angle
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle?
Very rarely.
How do you find an angle in quadrangle without a protractor?
Measure the two sides adjacent to the angle and the diagonal at the far ends of these sides. Then use the cosine rule to calculate the angle.
How do you find the measure of a tangent angle?
Take the inverse tangent -- tan-1(opposite side/adjacent side)
How do you find an angle with in an adjacent angle?
usea protracter
If two angles are congruent, adjacent, and supplementary. What is the measure of each angle?
90 degrees is the angle
How do you find the measure of an angle by using its tangent?
You would have to use its opposite tangent, tan-1on your scientific calculator. It would be tan-1(opposite side/adjacent side), and you must have the opposite and adjacent sides of the angle you are trying to solve.
Is it true or false the measure of an exterior angle and the adjacent interior angle sum to 180 degress?
True
If two angles are adjacent and complementary. What is the measure of each angle?
Can't be determined
