There are many ways of finding angles in triangles...one of which is to get a protractor, of course...
Also, if you know two angles, you can find the third by just subtracting the sum of the two angles from 180, which is the total number of degrees in any triangle.
if the triangle has one right angle in it
right angle!
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
By using Pythagoras' theorem for a right angle triangle.
It is the longest side of a right angle triangle.
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
if the triangle has one right angle in it
if the angle of a triangle are in the ratio 7:11:18,find the angle
It has a 90 degree angle..
right angle!
You can find the angle of a triangle within a circle segment using the circle theorems.
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
By using Pythagoras' theorem for a right angle triangle.
It is the longest side of a right angle triangle.
use a protractor
It is a right angle triangle and its largest angle is 90 degrees
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
