commission is what you get when you make sales
The two sides marked 7 are congruent.
Sides AC and AD are congruent.
Sides BC and ED are congruent.
By SSS, the triangles are congruent.
Also, angles BAC and EAD are congruent, so by SAS, the triangles are congruent.
Answer: A. yes, by either SSS or SAS
Answer:
e
Step-by-step explanation:
it’s adding a number by itself the same as multiplying it by 2
I think instead of "conjunction" it should say "conjecture"
Anyways, draw out a quadrilateral (see figure 1 attached). It can be any figure with 4 sides. Label the angles as A, B, C and D. The conjecture to prove is that A+B+C+D = 360. In other words, the sum of the four angles of any quadrilateral is always 360 degrees.
Draw a segment from A to C. This segment will cut the quadrilateral into two triangles. Re-label angle A to angle E and F. Do the same for angle C (label it G and H). Essentially, angle A = E+F and angle C = G+H.
See figure 2. Notice how I've color-coded things. The blue angles correspond to one triangle while the red angles correspond to the other triangle.
Since we know that three angles of a triangle always add to 180, we can say
B+G+E = 180
F+D+H = 180
Add the two equations (add left side separately; do the same for the right side)
Doing so leads to
B+G+E+F+D+H = 180+180
(E+F) + B + (G+H) + D = 360
A+B+C+D = 360
Which proves the conjecture
