A triangle with a 90° angle is called a "right triangle."
A right angle triangle
right angle=90 degrees and a right triangle has one side of it that forms a 90 degree angle...as for the naming "right" don't know but it refers to 90 degree angle
Because the phrase 'right angle' indicates 90 degrees whereas there is no such angle as a 'left angle'
It is a right triangle or right-angled triangle. The right-angle is 90 degrees.
A triangle with one angle measuring 90˚ is a right triangleIt's a right triangle because the 90˚ angle is a right angle
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° angle is called a "right triangle."
Any triangle with a 90 degree angle is called a right triangle.
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
A right angle triangle.
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
