Equilateral: All angles of a triangle are 60 degrees, they are all equal.
Right: One angle is 90 degrees (right angle), the other 2 are acute.
Acute: All three angle are acute (less than 90 degrees).
Obtuse: One obtuse (greater than 90 degrees) angle.
Isosceles: Two sides of equal lenght, 2 equal angles.
Scalene: No sides of equal length, angles are all different in size.

...a right triangle.
is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
equilateral= all sides are the same length isosceles = two sides are the same, one is different
A triangle in which all sides are of equal length is an equilateral triangle.A triangle in which two sides are of equal length is an isoceles triangle.A triangle in which all sides are of different length is a scalene triangle.
is it a right triangle if the measure is 5 7 and 9
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.
The three interior angles add up to 180°. (180° is the measure of a triangle)
There are three angles in a triangle but to measure them you would use a protractor.
it depends on the triangle
Only an equilateral triangle has rotational symmetry.
A triangle on a concave surface.
