It's a general reasoning technique. If you can see that x is congruent to y then what goes for y also goes for x. Congruent just means is the same for the properties we are considering at the moment.
If the problem is (5x+1) and your trying to figure out X. The answer is 12. (APEX)
5.3 = 2x so x = 5.3/2 = 2.65
Suppose each base angle is x degrees. Then sum of all three [internal] angles is 180 deg So that 28 + x + x = 180 ie 2x = 152 and then x = 76 deg The length of the congruent sides is irrelevant.
If angle A is congruent to angle B, then angle B is congruent to angle A.If X is congruent to Y then Y is congruent to X.
The Symmetric Property of Congruence: If angle A is congruent to angle B, then angle B is congruent to angle A. If X is congruent to Y then Y is congruent to X.
The two legs that are congruent can be called x and x respectively, while the third non-congruent leg is ?2
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.

X is 4 cm.
x and y are complementary so x + y = 90 and so y = 90 - x z and q are complementary so z + q = 90 and so q = 90 - z x = z so 90 - x = 90 - z that is y = q
No, a 2 by 4 rectangle is not congruent to a 4 by 8 rectangle. They are similar, but the 4 by 8 rectangle is 4 times bigger than the 2 by 4.
Congruent ones. A cube of side x has a volume of x3. Any other cube, of volume x3 must have sides of length x and so the two cubes must be congruent.
