Just because they look the same does not mean they are. Normally if sides are congruent they are marked by the same indicator. Which is usually a line, number, or letter. Same thing with angles, except angles would not use lines to indicate congruency. If you have any three congruent parts on triangles (the number may change due the shape) then those triangles are congruent.

When do you use CPCTC?
You can only use CPCTC after you prove the 2 triangles congruent.
To use the HL theorem to prove two triangles are congruent the triangles must be right trianglesWhich other conditions must also be met?
1. There are two right triangles. 2. They have congruent hypotenuses. 3. They have one pair of congruent legs.
what-Norman was asked 2 prove that all right angles r congruent. He was provided a diagram with several right angles. Norman measured each angle with a protractor & found that they each measured 90°.?
A+
What are the five ways to prove a triangles congruent?
The 5 ways to prove that two triangles are congruent are to find equal: 1) side-side-side 2) side-angle-side 3) angle-side-angle 4) angle-angle-angle 5) hypotenuse-leg
How can you prove a triangle ABC is isosceles if angle BAD is congruent to angle CAD and line AD is perpendicular to line Bc?
Given: AD perpendicular to BC; angle BAD congruent to CAD Prove: ABC is isosceles Plan: Principle a.s.a Proof: 1. angle BAD congruent to angle CAD (given) 2. Since AD is perpendicular to BC, then the angle BDA is congruent to the angle CDA (all right angles are congruent). 3. AD is congruent to AD (reflexive property) 4. triangle BAD congruent to triangle CAD (principle a.s.a) 5. AB is congruent to AC (corresponding parts of congruent triangles are congruent) 6. triangle ABC is isosceles (it has two congruent sides)
What is a figure with 2 congruent segments and 3 congruent angles?
It could be any number of polygons with 4 or more sides.
What has 2 sides that are congruent?
Many things have 2 sides that are congruent, including isoceles triangles, any regular polygons or polyhedrons, rectangles, etc.
How can you tell 2 polygons are congruent?
When they are identical to each other in size and angles
What term describes 2 polygons when all the angles and lines are the same?
In math when 2 polygons have the same angles, lines and size, they would be congruent.
What figure has 2 congruent polygons as bases?
A prism. A triangular prism has two congruent triangles as bases, rectangular prism, pentagonal prism, etc.
What is a figure that has 2 congruent polygons as bases and has only one curved surface?
I am not sure that such a surface can exist.
What is a 3 dimensional figure with 2 congruent parellel bases that are polygons?
If, by parellel you mean parallel, the answer is a prism.
When do you use CPCTC?
You can only use CPCTC after you prove the 2 triangles congruent.
What is a 3 dimensional figure with 2 congruent parallel bases that are polygons?
I have no f*cking idea and i am a f*cking 7th grader.
How can you tell both shapes are similar?
to prove two triangles are similar, get 2 angles congruent
How do you prove the diagonals of an isosceles triangle congruent?
You can't because triangles do not have diagonals but an isosceles triangle has 2 equal sides
What is a polyhedron with 2 congruent parallel bases called?
A parallelogram or trapezoid.No!A parallelogram or a trapezoid are polygons (2-dimensional). A polyhedron, or 3-dimensional object, with parallel congruent bases is a prism.A prism. To give it fuller description, an "n-gonal prism" where the "n-gon" refers to the 2-d name of the bases.
