if two of the sides are proportional and the included angles are congruent then the triangles are SIMILAR.
Answer: similar
Answer:
x = 45°
Step-by-step explanation:
<u>Vertical Angle Theorem</u>
When two <u>straight lines intersect</u>, they form two pairs of angles. The vertically opposite (non-adjacent) angles are <u>congruent</u> (equal).
From inspection of the given diagram, the <u>straight line with points C and D</u> and the <u>straight line with points F and G</u> intersect at <u>point E</u>.
Therefore, angles ∠FEC and ∠DEG are vertically opposite, and so they are equal.
From inspection of the diagram:
- ∠FEC = x°
- ∠DEG = 20° + 25° = 45°
Therefore:
⇒ ∠FEC =∠DEG
⇒ x = 45°
D ( -b, h)
E ( b, h)
F ( b, -h)
G ( -b, -h)
from 0 to E, x=b, from 0 to DG, x= -b
from 0 to DE, y=h, from 0 to GF, y= -h
