A polygon where all angles are congruent is called what?
Equiangular. It is NOT regular unless all the sides are also equal and, unlike in a triangle, that does not follow from the angles being equal.
What is a triangle with 1 right angle called?
A Right- Angled triangle. Also Equilatertal ; the three sides are of equal length, and the three angles are all 60 degrees. Isosceles ; two sides of equal lnegth, and two angles of equal size. Scalene ; all three sides are unequal in length, and all three angles are different. In all cases the sum on the three interior angles equals 180 degrees.
What are the classification of triangle according to sides and angles?
Classification of Triangles According to anglesIf one angle of a triangle is a right angle (90°), then it is called a Right triangle. Note that the other two angles are acute.If all the angles of a triangle are acute (less than 90°), then it is called an acute angled triangle.If one angle of a triangle is obtuse (greater than 90°), then it is called an obtuse triangle. Note that the other two angles are acute.According to sides:If any two sides of a triangle are equal, then it is called an Isosceles Triangle. In ABC, AB = AC ABC is isosceles.If all the three sides of a triangle are equal, then it is an Equilateral Triangle. In ABC, AB = BC = CA ABC is equilateral.If no two sides of a triangle are equal, then it is called a Scalene Triangle. In ABC, AB BC CA. ABC is scalene.
What is the definition to acute triangle?
A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.
A set of three points equidistant around a point is called an?
A set of three points equidistant around a point is called an equilateral triangle. In geometry, an equilateral triangle is a triangle in which all three sides are equal in length. The angles in an equilateral triangle are also equal, each measuring 60 degrees.
