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,
Using trigonometry: tangent = opposite/adjacent
Raise a perpendicular from one arm to the other. This creates a right angled triangle. Measure two of the sides of the triangle and use the appropriate trigonometric ratio and a computer/calculator/slide rule/tables to convert the ratio to an angle. eg measuring the side adjacent to the angle and the length of the side opposite the angle, which is the perpendicular raised, dividing the length of the opposite side by the adjacent side gives a value which can be looked up in arc tan tables (etc) to get the angle.

Yes, there is such thing as a right-angled triangle. The measure of the adjacent and opposite form together to create a 90 degree angle. That means that the measure of the hypotenuse and adjacent must be 45 degrees and the hypotenuse and opposite measures to 45 degrees.

The side adjacent to the forty degrees of a right triangle with a hypotenuse of 6 meters and one of its angles measuring forty degrees is: 4.6 meters.

It depends on what measure you want: the perimeter, the area, the size of the angles or something else. The question is not specific enough.

Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

they can be but are not always. for example, in a square, each interior angle is 45 degrees. Adjacent simply means that one next to another and congruent means having the same measure. So in this example, adjacent angles are congruent. However, in a scalene triangle, no two angles are the same and therefore cannot be congruent. I hope this is what you are asking Dave
is it a right triangle if the measure is 5 7 and 9
Wavelength is the measure of distance between adjacent crests or troughs.
