Proportions would be the best way; given the sides of the triangle, use ratios to find the corresponding side on the congruent triangle.
For example: if three sides are given, 3, 4, and 5, and you had to solve a triangle with lengths 9, 12, and x, this is how you would do it.
Given the triangles are congruent, 4/5 = 12/x
4x = 60
x = 15

How do you find a triangle congruent by cpctc?
A triangle if not found congruent by CPCTC as CPCTC only applies to triangles proven to be congruent. If triangle ABC is congruent to triangle DEF because they have the same side lengths (SSS) then we know Angle ABC (angle B) is congruent to Angle DEF (Angle E)
What shape has no congruent sides?
If a triangle does not have the same length side as another triangle the sides are not congruent.
What is Angle Side Angle?
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
How do you find the missing side from a right triangle?
to find the missing side of a right triangle you need the pythagorean theorem. A2 + B2 = C2. c is the longest side and a and b is the other sides. no particular side is a or b just the longest side is c.
If two triangles have three pairs of congruent angles the the triangle is congruent?
Yes they are. Or they could have three pairs of congruent sides, or they could have one pair of congruent angles and two pairs of sides. As far as a triangle goes, if you have at least three pairs of congruent sides or angles they are congruent. This answer is wrong. The triangles are only similar. For congruent trisngles we have the following theorems = Side - side - side, Side - Angle - side , Angle - angle - side, Right triangle - hypotenuse - side.
