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

What is a triangle with two sides the same and one side odd?
isoceles
What is a triangle called with no two angles measuring the same size?
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.
What relationships exist between the two congruent sides of an isosceles triangle and its base?
The angles where the equal sides meet the third side of the triangle are equal angles.
What is a scailene triangle?
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.
What kind of triangle has 2 equal side lengths?
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°).
What shape has three side and two of your angles are equal?
Isoceles Triangle
What is a polygon with 2 angles congruent and the lengths of the side are proportional?
isoceles triangle
What is a triangle with two sides the same and one side odd?

An isoscles triangle is a triangle that has?
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.
What is the measure of the sides of an isosceles triangle if one side equals 12.1?
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.

How many congruent sides does a isosceles triangle have?
An isosceles triangle has two congruent sides.
What does an equilateral triangle and an scalene triangle different?
An Equilateral triangle has three sides with the same length.A Scalene triangle has 3 sides that each have different lengths.An Isoceles triangle has 2 sides that have the same length and one side that has a different length.Hope this helps-Lil O's
What is the difference between an isosceles triangle and a right triangle?
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.
What relationships exist between the two congruent sides of an isosceles triangle and its base?
The angles where the equal sides meet the third side of the triangle are equal angles.
If you fold a square piece of paper so that opposite vertices are touching what shape do you get?
you get an isoceles triangle which is a triangle that has two sides equal and the other side is a different length.
What is a triangle with three equal sides called?
This traingle is an equilateral traingle: which consists of all the three sides and angles to be congruent. The angles inside the triangle, just like any normal traingle, add up to be 180 degrees. The opposite of this traingle is the Scalene triangle which has all the three sides to be Uncongruent and has different angles. All the angles of ALL traingles still add up to 180 Degrees. The Isoceles triangle consists of two equal sides and one extravagantly large one side. Therefore, because of the previous properties, an isosceles traingle has two congruent angles and usually one obtuse or acute angle. The last triangle, the right triangle, has one right angle. It is the only triangle that is capable with triginomical ratios and the Pythagorean Theorem.
