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.
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.
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.
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.
What is the formula for finding a missing side on a congruent triangle?
It is the same length as the corresponding side on the other triangle.
If a triangle has one congruent side then is it a scalene triangle?
if it has one congruent side it is a scalene triangle. if it has a pair of congruent sides it is an isosceles triangle. if all the sides are congruent it is an equilateral triangle
A triangle with no congruent side?
................ scalene triangle ................ =)
What triangle side are all congruent?
An equilateral triangle has three congruent sides.
How do you find the missing side of a triangle with a perimeter of 40?
It depends on what is known about the triangle.
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)
Are all the side congruent on a triangle?
Only an equilateral triangle are all sides congruent
Why is pythagorus theorem useful?
to find the missing side of a triangle
A triangle with no congruent side is called?
A scalene triangle.
How do you find a missing side of a triangle?
The way to find the missing side of a triangle-THIS ONLY WORKS ON RIGHT ANGLED TRIANGLES-is square both sides seperately and then add them together to give you the square of the missing side-find the square root and that is the size of the missing side-eg. if you have a RIGHT ANGLED TRIANGLE with sides of 3inch and 4inch then (3x3) + (4x4) = 25 so the square root of 25 is 5 meaning the missing side is 5inch.
What shape has no congruent sides?
If a triangle does not have the same length side as another triangle the sides are not congruent.
How can you find a missing side or angle of a right triangle?
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
