A right triangle because the 90 degree angle creates a corner.
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
An obtuse triangle is a triangle that has one angle greater than 90 degrees.
A right triangle has a 90 degree angle in it. This is not to be confused with a wrong triangle, which has two 90 degree angles.
It is a right angle triangle because it has a 90 degree angle and the 3 angles add up to 180 degrees.
A right triangle because the 90 degree angle creates a corner.
It's an acute angled 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 right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
There is one 90 degree angle in a right angle triangle
It is an isosceles triangle.
A 90o angle is also called a Right Angle, so a triangle that has one 90o angle is a Right angle triangle.
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
An Obtuse Triangle
An obtuse triangle is a triangle that has one angle greater than 90 degrees.
If it has one 90 degree angle then it is a right triangle.
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
