The diagonal AC is drawn in parallelogram ABCD Which method can NOT be used to prove that AABC is congruent to ACDA?
diamong [38]

Answer:

B SSA

Step-by-step explanation:

Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.

However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.

A team has 3 wins for every loss they loss games how many did they win??
OLEGan [10]
The team has lost only 6 games (according to the comments). Let's say "x" is the amount of losses and "y" is the amount of wins.

For every loss, they have 3 wins, so in the end, this would be the equation:
y = 3x
or
y = 3 \times x
Although the first one would be the easier and most understandable to read.

So:
y = 3(6)
would equal

Answer:

  x = 22.5°

Step-by-step explanation:

Angle BED ≅ angle EBC = 6x, so angle BEA = 4x. The angles FEB and BEA form a linear pair, so we have ...

  4x +4x = 180°

  x = 22.5° . . . . . . divide by 8

_____

BED and EBC are "alternate interior angles" with respect to transversal BE crossing parallel lines DE and AC.
