CPCTC stands for "corresponding parts of congruent triangles are congruent." This means that, if any two triangles are proven by any method to be congruent, then all corresponding parts of the triangles (eg angles, lengths, areas) are also congruent. This theorem can also be extended to CPCFC (congruent parts of congruent figures are congruent) to be used with any two polygons or polyhedrons (3D shapes).

To do this, check to see if the ... If all three pairs of angles for two given triangles are congruent does that mean that the triangles are congruent? ...

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

47 - 90 = 43

43 - 180 = x

x = 137
