It is a right angle triangle
Any triangle that has an angle measuring 90 degrees is a right triangle.
A triangle with one angle measuring 90˚ is a right triangleIt's a right triangle because the 90˚ angle is a right angle
An angle measuring exactly 90 degrees is a right angle.
right angle triangle
A triangle has 180 degrees.A right triangle has exactly one angle measuring 90 degrees.If you know that one of the other angles of the triangle is 20 then your third angle is:180-90-20 = 70 degrees.
An obtuse triangle.
right angle right angle
An obtuse angle is an angle measuring between 90 and 180 degrees
Obtuse. Any angle measuring greater than 90 degrees but less than 180 is considered obtuse. An acute angle is any angle measuring between 0 and 90 degrees. A right angle is an angle measuring exactly 90 degrees while a straight angle measures exactly 180 degrees.
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
