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.
How d I draw a pair of adjacent supplementary angle so that one angle has the given measure?
To draw a pair of adjacent supplementary angles, start by drawing a straight line, which will serve as one side of both angles. Choose one angle measure, and use a protractor to measure that angle from the line, marking its vertex. Then, since supplementary angles add up to 180 degrees, subtract the given angle measure from 180 to find the measure of the second angle. From the vertex, use the protractor to measure and mark the second angle adjacent to the first, ensuring they share a common side along the straight line.
How do you find a mesaure of an exterior angle on a triangle?
To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.
How do you find the exterior angle of a triangle?
To find the exterior angle of a triangle, first identify the two adjacent interior angles that form the exterior angle. The measure of the exterior angle is equal to the sum of these two interior angles. Alternatively, you can use the property that each exterior angle is equal to 180 degrees minus the adjacent interior angle. This relationship holds for all triangles.
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)

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
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,
