Consider a right triangle. One of the exterior angles 90 degrees.
A triangle with a 90° angle is called a "right triangle."
An exterior angle is on the outside of a shape. For example, the internal angle of a corner of a square is 90 degrees. 360 degrees less 90 degrees equals 270 degrees. Therefore, the exterior angle of a right-angle is 270 degrees. Search Google with "exterior angle" for more info.
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.
a triangle has 180 degree but each exterior has 90 degree .
Consider a right triangle. One of the exterior angles 90 degrees.
is an exterior angle of a quadrilateral always sometime or never 90 degrees
an interior angle + and exterior = 180 Angle A: 180-30=150 Angle B: 180-60=120 Angle C: 180-90=90 Angle D: 180-120=60 SO WHATS THE ANSWER!!!?????
A isosceles right angle triangle will have 2 equal interior angles of 45 degrees and 1 angle of 90 degrees with its largest exterior angle being 180 -45 = 135 degrees.
Any triangle that has an angle measuring 90 degrees is a right triangle.
Exterior angle of a square is 90 degrees Exterior angle of a regular pentagon is 72 degrees
Square = 90 degrees Pentagon = 72 degrees
A triangle with one angle over 90 degrees is an obtuse triangle.
