Answer: c
Step-by-step explanation:
As C is the mid-point of BD.
Therefore, BC=DC ...(i)
As AB ⊥ BD and ED ⊥ BD
So, ∠ABC= 90° and ∠EDC= 90°
Therefore, ∠ABC=∠EDC= 90° ...(ii)
As two line segments, AE and BD intersect at point C, so the vertically opposite angles are equal.
Therefore, ∠BCA=∠DCE ...(iii)
Now, in ΔABC and ΔEDC,
Angle, ∠BCA=∠DCE [ from equation (iii)]
Side, BC=DC [ from equation (i)]
Angle, ∠ABC=∠EDC [ from equation (ii)]
So, by ASA property of congruency, ΔABC and ΔEDC are congruent
Hence, ΔABC ≅ ΔEDC.
Answer:
16, 49, 121
Step-by-step explanation:
Answer:
The area is 6.4cm, the perimeter is 12cm
Step-by-step explanation:
The formula to calculate area is
![A=\frac{h_{b}*b}{2}=\frac{3.2*4}{2}=6.4](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bh_%7Bb%7D%2Ab%7D%7B2%7D%3D%5Cfrac%7B3.2%2A4%7D%7B2%7D%3D6.4)
Where
is the height
And for the perimeter, you just add up the size of the sides.
