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.
It has 180 degrees, but one angle of the triangle has to be 90 degrees
An obtuse angled triangle.
Right angled triangle because the third angle must be 90 degrees.
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
It is a right angle triangle
An obtuse triangle.
Obtuse angle
yes it is 180
An obtuse triangle
obtuse
there can be only one angle measuring more than 90 degrees.. as sum of angles in a triangle is 180 degrees. all the angles cannot exceed 90. A triangle in which one angle is greater than 90 degrees is an obtuse angled 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.
It is an obtuse triangle if its 2 other acute angles are different in sizes.
A triangle with one angle over 90 degrees is an obtuse triangle.
right triangle
It has 180 degrees, but one angle of the triangle has to be 90 degrees
