a. sss.
b. asa.
c. sas.
d. hl.

Option is D.

The congruence theorem that can be used to prove  △BAE ≅ △CAD  is HL (Hypotenuse and leg of a right triangle.)

Step-by-step explanation:

From the Figure:

Consider  △BAE ≅ △CAD

∴

Therefore, by HL i.e, (Hypotenuse and leg of a right triangle) which implies that two right angle triangle are congruent if their hypotenuse and one corresponding leg of the triangle are equal.

Hence,   by HL congruence theorem.

The shape of the graph is sinusoidal

The domain is from  θ = -∞ to +∞

The range is from r = 2 to -2

The maximum r value of the graph is r = 2

The graph is continuous and bounded with symmetry about the line origin and the y-axis

The graph has no asymptotes

Step-by-step explanation:

The graph r = -2·cos(5θ) and table of values are attached

The maximum r can be found by differentiating the function as follows;

sin(5·θ) = 0, hence the maximum value occurs at θ = 0 or θ = π

Which gives, r = -2 and 2. Therefore, maximum r = 2 and minimum r = -2.
