How do you find out if a triangle is a right angle triangle given only the length of each side?
Measure 3 of any unit on one of the sides that you suppose have a right angle. Measure 4 of the same unit an the oher side you suppose has a right angle. the distance between the marks you made should mbe 5 if it is a right angle

What is the measure of the angle named x?
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.

Find the measures of the angles of a triangle if the measures of one angle is twice the measure of a second angle and the third angle measures 3 times the second angle decreased by 12?
Let the second angle of the triangle be A. Then angle 1 = 2A : and angle 3 = 3A - 12 The internal angles of a triangle total 180° therefore :- 2A + A + (3A - 12) = 180 6A - 12 = 180 : 6A = 192 : A = 32 The angles measure 64° , 32° and 84° .

How do you find the side of a triangle?
To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.

The measure of the vertex angle of an isosceles triangle is 15 degrees more than the measure of each base angle. Find the number of degrees in each angle of the triangle.?
Let x be the measure of the base angle in degrees, so the measure of the vertex angle in degrees it will be x + 15. Since the triangle is an isosceles triangle, where the base angles are congruent, we can form the equation: 2x + (x + 15) = 180 3x + 15 = 180 subtract 15 to both sides; 3x = 165 divide by 3 to both sides; x = 55 x + 15 = 55 + 15 = 70 Thus, each base angle is 55° and the vertex angle is 70°.
How do you find a missing exterior angle of a triangle?
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
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.
