40 degrees
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
since it is a right triangle there is one 90 degree angle and another of the angles is 45 degrees. there is 180 degrees in a triangle so the missing angle is 45 degrees.
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
No, because a triangle's angles can only measure up to 180 degrees. A right angle is 90 degrees, plus another 100 degree angle would be 190 degrees.
The third angle is 68 degrees which makes it a scalene triangle
100
In a right triangle the greatest angle is 90 degrees.
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
