Answer:
If it is a square kitchen the walls will be 12 units long
Step-by-step explanation:
To get from 2,4 into -10,4 you move down 12 units
The perimeter is 3 times the length of each side:
p = 3s
If the perimeter is at most 45 cm, then
p ≤ 45 cm
3s ≤ 45 cm
45 cm
s ≤ —————
3
s ≤ 15 cm
So each side is at most 15 cm.
I hope this helps. =)
Answer: AA similarity theorem.
Step-by-step explanation:
Given : AB ∥ DE
Prove: ΔACB ≈ ΔDCE
We are given AB ∥ DE. Because the lines are parallel and segment CB crosses both lines, we can consider segment CB a transversal of the parallel lines. Angles CED and CBA are corresponding angles of transversal CB and are therefore congruent, so ∠CED ≅ ∠CBA.
Also ∠C ≅ ∠C using the reflexive property.
Therefore by AA similarity theorem , ΔACB ≈ ΔDCE
- AA similarity theorem says that if in two triangles the two pairs of corresponding angles are congruent then the triangles are similar .
