Use the cosine rule:
a2 = b2+c2 - 2bc*cos A

What is the difference between a triangle and an isosceles triangle?
An isosceles triangle has to have two sides of equal length. An isosceles triangle has to have two sides of equal length.
What is the difference between an isosceles and a regular triangle?
An isosceles triangle has two equal sides and one that isn't. A regular triangle has three equal sides.
What is the difference between an isosceles triangle and a scalene triangle?
An isosceles triangle has two equal side; a scalene triangle has no two equal sides.
What is the differences between an isoceles triangle and an obtuse triangle?
-- An isosceles triangle can also be an obtuse triangle but it doesn't have to be. -- An obtuse triangle can also be an isosceles triangle but it doesn't have to be. So there's no consistent diferences betwen them.
What is the difference isosceles triangle and a scalene?
An isosceles triangle has two (or more) sides of equal length, while a scalene triangle has no correlation between side lengths/angle size.
What is the difference between a triangle and an isosceles triangle?
An isosceles triangle has to have two sides of equal length. An isosceles triangle has to have two sides of equal length.
What are the differences between an isosceles triangle and an equilateral triangle?
An isosceles triangle only has 2 equal sides while an equilateral triangle has 3equal sides
What is the difference between an isosceles and a regular triangle?
An isosceles triangle has two equal sides and one that isn't. A regular triangle has three equal sides.

What is the difference isosceles triangle and a scalene?
An isosceles triangle has two (or more) sides of equal length, while a scalene triangle has no correlation between side lengths/angle size.
How many obtuse angles could an isosceles triangle have?
An Isosceles Triangle is a triangle with all angles less than 90o So there are no obtuse angles (between 90o to 180o).
What is the difference between an isosceles and an scaline triangle?
An equilateral triangle is a triangle where all of the sides are of equal length. An isosceles triangle is a triangle that has only two sides that are of equal length.
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 is the difference between a right triangle and an isosceles triangle?
A right triangle can be an iscosceles or scalene triangle. A right triangle is a triangle that therein has one right angle and 2 acute angles. An isosceles triangle has two sides of the same length and one different.
What is the difference between a scalene an isosceles and an equilateral triangle?
A scalene triangle has 3 sides of different lengths An isosceles triangle has 2 sides of equal lengths An equilateral triangle has 3 sides of equal lengths
What is a base angle of an isosceles triangle?
The base angles of an isosceles triangle are the two angles that are equal to each other. They can be between 89.999...o and 0.000000..01o.
