AD || BC
<span>• AB = CD </span>
<span>• ∠BAD = ∠CDA (a given condition ∵ ABCD is an isosceles trapezium) </span>
<span>The diagonals AC and BD create two ∆'s: ∆ABD, and ∆ACD </span>
<span>The two ∆'s are congruent (SAS). </span>
<span>(S): AB = CD </span>
<span>(A): ∠BAD = ∠CDA
</span><span>(S): AD = DA (common side) </span>
<span>
The corresponding sides of the two ∆'s, BD and AC, are also congruent. </span>
<span>(the two diagonals of the trapezium/trapezoid)
</span>
Answer:
yes
Step-by-step explanation:
When the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle. 6: 8: 10 follow those terms, henceforth, then the triangle is a right triangle
110 - -34
110 + 34
144
The difference between the two temperatures is 144 F
It is proportional because it has a direct relationship.
The standard way to write it is
7 x 8 = 56
