Short Answer: no <br /><br /> Long Answer: <br /> Most people consider Euclidean Geometry when taking about standard shapes such as triangles and squares. <br /><br /> In Euclidean Geometry: all equilateral triangles have angles of 60Â°. Therefore an equilateral triangle doesn't have a right angle. <br /><br /> However, in Non-Euclidean Geometry (Elliptic Geometry) a triangle can have all angles at 90Â°. Consider going for a walk at the North Pole.
Right-Angled Triangles. A right-angled triangle (also called a right triangle) is a triangle with a right angle (90Â°) in it. The right angled triangle is one of the most useful shapes in all of mathematics! (It is used in the Pythagoras Theorem and Sine, Cosine and Tangent for example). Try it yourself (drag the points): Two Types. There are two types of right angled triangle: Isosceles right-angled triangle. One right angle Two other equal angles always of 45Â° Two equal sides . Scalene right-angled triangle. One right angle Two other unequal angles No equal sides
