If you know the length of the sides of a triangle you can find all the angles of the triangle using the Law of cosines such as:
Step 1.
cos A = (b^2 + c^2 - a^2)/(2bc)
cos B = (a^2 + c^2 - b^2)/(2ac)
cos C = (a^2 + b^2 - c^2)/(2ab)
Step 2.
Find the arc cosine A, arc cosine B, and arc cosine C in order to find the angles A, B, and C.

What are the 6 possible groups of triangles?
Right triangle= has a right angle Acute triangle= has an acute angle Obtuse triangle= has an obtuse angle Equilateral triangle= all sides are the same length Scalene triangle= has no sides the same length Isosceles triangle= has only two sides the same length the triangles here make perfict dildose and condoms
What does right isosceles mean?
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
How do you find side of scalene triangle given a length and an angle?
You don't. It takes more than one side and one angle to determine a triangle. If you have two sides and the angle between them, or one side and two angles, you can do it.
What triangle has 2 sides the same and the same length and a angle of 90 degrees?
An isosceles right angle triangle
What triangle has all sides the same length and has a right angle?
equilateral right triangle
A triangle with 2 equal sides but no right angle?
a triangle with two sides the same length and no right angle
What right triangle has legs of equal length?
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
What is the name of A triangle with sides of no equal length?
A triangle with no right angle and sides of different lengths is a scalene triangle.

What is a right scalent triangle?
A right scalent triangle is a triangle with a right angle and no sides equal in length.
What is a shape that like a triangle with the same sides?
the type of triangle is an equilateral triangle, meaning that all three sides are the same length and angle
What is the length of the triangle if it's sides are 9 and 15?
It's a right angle triangle and its length is 12 units of measurement.
Which is a triangle with no sides the same length and an interior angle measuring 90 degrees?
This is a right triangle.
