Answer:

Explained below

Step-by-step explanation:

We are told that; Line CA = Line CD

Thus, it means that;

∠ACD = ∠BCD

Line CE is equal in both triangles. Thus,

Line CE = Line CE

This then implies that;

ΔACD = ΔBCD

Finally, it means that;

Line AD = Line BD

Since Line AD = Line BD, it means the perpendicular line from point C touching D is a bisector of Line AB

Which are the side lengths of a right triangle? Check all that apply.
S_A_V [24]

Answer:

3, 14, and sqrt205.

2,9, and sqrt85.

Step-by-step explanation:

Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:

3^2 = 9 , 14^2 = 196.

9 + 196  = 205  which is the square of sqrt205.

So this is a right angled triangle.

6^2 + 11^2 = 36 + 121

= 157 Not right-angled.

19^2 + 180^2  = 32761  Not right-angled.

3^2 + 19^2 = 370    Not right-angled.

2^2 + 9^2 = 85, So this is right angled..
