Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:

en.wikipedia.org/wiki/Sides_opposite_equal_angles

An equilateral triangle has the same pattern on all 3 sides, an isosceles triangle has the same pattern on just 2 sides, and a scalene triangle has different patterns on all sides since no sides are equal. Similarly, patterns of 1, 2, or 3 concentric arcs inside the angles are used to indicate equal angles.

A triangle that has two equal sides is called an Isosceles Triangle. It has two sides that are the same length and one side that is a different length. But for it to be a triangle, all the angles ...

The lengths of two sides of a triangle can be equal in some cases and it is possible in the case of isosceles triangle. The equality property of two sides make isosceles triangle to have symmetry property. Hence, the angles opposite to the two equal length sides are always equal geometrically.

An isoceles triangle has only 2 equal sides and angles. An equilateral triangle has three of each. Any regular polygon has at least 2 equal sides and angles.

The triangle above is isosceles because there are lines marking two of its equal sides. Angle ‘a’ must be equal to 50° because these two angles are opposite the two equal sides. The two equal angles, 50° and 50°, add to make 100°. To find angle ‘b’, we subtract 100° from 180°. This equals 80°.

An isosceles triangle is a triangle with two sides of the same length. These two equal sides always join at the same angle to the base (the third side), and meet directly above the midpoint of the base. You can test this yourself with a ruler and two pencils of equal length: if you try to tilt the triangle to one direction or the other, you cannot get the tips of the pencils to meet.

The ratio of sides doesn’t equal the ratio of angles. Don’t assume that if one side of a triangle is, say, twice as long as another side that the angles opposite those sides are also in a 2:1 ratio. The ratio of the sides may be close to the ratio of the angles, but, for a scalene triangle, these ratios are never exactly equal. Isosceles ...
