Let the sides be abc and their opposite angles be ABC and so:
Using the cosine rule angle A = 67.38 degrees
Using the cosine rule angle B = 67.38 degrees
Angle C: 180-67.38-67.38 = 45.24 degrees

An equilateral triangle is a triangle with all sides & angles having the same measure.An isosceles triangle is a triangle with 2 sides & angles measuring the same, leaving one angle/side to be different.A scalene triangle is a triangle with no sides and/or angles measuring the same length.
The angles where the equal sides meet the third side of the triangle are equal angles.
A scalene triangle is one in which all angles are different and all sides are different. An isosceles triangle has two angles the same and two sides the same. An equilateral triangle has all three angles the same (60o) and all three sides the same. A right angle triangle has one of the angles 90o; the side opposite the right angle (90o) is called the hypotenuse.
An isoceles triangle has 2 congruent sides of equal length, and one of a different length.(If all three side lengths are the same, you have an equilateral triangle, which is also equiangular, each angle 60°).

An isoceles triangle is a triangle which has exactly two sides of equal length. The third side can be longer or shorter than the other two. The two sides being of equal length means that two of the angles are of equal size (not the one between the two equal-sized sides).Other types of triangleAn equilateral triangle is one where all three sides are of equal length and so all angles are of equal size. A right-angled triangle is one which has a right angle in it. It can be either an isoceles triangle or a scalene triangle. Scalene triangles are triangles where every side is of a different length and every angle is of a different size.
If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.

In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle has TWO sides of equal length but and equilateral triangle has THREE sides of equal length.
The angles where the equal sides meet the third side of the triangle are equal angles.
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
you get an isoceles triangle which is a triangle that has two sides equal and the other side is a different length.
