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.
You can only use CPCTC after you prove the 2 triangles congruent.
1. There are two right triangles. 2. They have congruent hypotenuses. 3. They have one pair of congruent legs.
A+
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
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)
It could be any number of polygons with 4 or more sides.
Many things have 2 sides that are congruent, including isoceles triangles, any regular polygons or polyhedrons, rectangles, etc.
When they are identical to each other in size and angles
In math when 2 polygons have the same angles, lines and size, they would be congruent.
A prism. A triangular prism has two congruent triangles as bases, rectangular prism, pentagonal prism, etc.
If, by parellel you mean parallel, the answer is a prism.
I am not sure that such a surface can exist.
You can only use CPCTC after you prove the 2 triangles congruent.
I have no f*cking idea and i am a f*cking 7th grader.
to prove two triangles are similar, get 2 angles congruent
The solid figure that has two congruent polygons as bases and lateral faces that are rectangles is called a prism. Specifically, if the bases are triangles, it is known as a triangular prism; if the bases are rectangles, it is a rectangular prism. The lateral faces connect the corresponding edges of the two bases, forming a three-dimensional shape.
You can't because triangles do not have diagonals but an isosceles triangle has 2 equal sides
