Answer: ASA congruency postulate
Step-by-step explanation:
Given: Parallelogram ABCD
To prove: ΔABD ≅ ΔBCD
Construction: Draw auxiliary line BD [see in the attachment]
Proof :- In ΔABD and ΔBCD
∠ADB=∠DBC [if lines are parallel, then its alternate interior angles are equal]
BD=BD [common]
∠ABD=∠BDC [if lines are parallel, then its alternate interior angles are equal]
⇒ΔABD ≅ ΔBCD [ASA congruency postulate]
⇒AD=BC and AB=CD [CPCTC]
- <em>ASA postulate tells if two angles and the included side of one triangle are equal to the corresponding parts of another triangle, then the triangles are congruent.</em>
<span> a(b – c) if a = -8, b = 12, and c = 4
</span><span> = -8(12 – 4)
= -8 (8)
= -64</span>
1.2 x 10^4 = 12,000
4.5 x 10^-3 = 4.5 x 1/(10^3) = 4.5/1000 = 0.0045
3.8 x 10^3 = 3,000
7.5 x 10^3 = 7,000
largest is 1.2 x 10^4
Answer:
75 degrees
Step-by-step explanation:
1. Find angle J.
The outside angle and angle J are supplementary, which means they add up to 180 degrees.
180 - 130 = 50.
So angle J is 50 degrees.
2. The angles in a triangle add up to 180. Add up angles J and K and subtract that from 180
50 +65 = 105
180- 105 = 75
