Answer:
Corresponding side lengths and angle measures of two congruent triangles are also congruent.
Step-by-step explanation:
If two triangles ABC and DEF are congruent (see below figure) to each other then, AB=DE, BC=EF, AC=DF and <A=<D, <B=<E, <C=<F
Answer:
Step-by-step explanation:
3a-2c+5ac=a
3a- a + 5ac= 2c
2a + 5ac = 2c
a ( 2 + 5c) = 2c
a = 2c / (2+5c)
