'a' and 'b' must both be acute, complementary angles.
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.
right triangle and the other angle would be 70 degrees. Hope I helped :)
It will be a right angle triangle with a 90 degree angle and 2 acute angles
The other acute angle in that triangle is 40 degrees.
70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70
Any triangle with a 90 degree angle is classified as a right triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
yes. a right triangle must have one angle that measures 90 degrees
right triangle
no a right triangle HAS to have an angle that measures 90 degrees.
Any triangle that has an angle measuring 90 degrees is a right triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle providing that the 3rd angle is 30 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.
A right angle is 90 degrees
A right angle triangle.
