Answer:
Yes, they are congruent by SAS postulate.
Step-by-step explanation:
Let us first name the vertices of both the triangles.
The labelled diagram is shown below.
Consider the triangles ABC and ACD
Statements Reasons
1. BC ≅ AC Given
2. ∠ ACB ≅ ∠ CAD Given
3. AC ≅ AC Common sides are congruent due to Reflexive property
As two corresponding sides and the included angles between them are congruent, therefore the two triangles are congruent by SAS postulate.
So, we can conclude that the given triangles are congruent.
Which seven?
070,000,000 would be in the 10 millions
700,000,000 would be in the 100 millions
calcuate whats in the inside and outside by multiplying
The technique I use is add up the numbers in the ratio. You get 2 + 4 + 4 = 10. Now to find the angles, you have to find the fraction of each number in the triangle. So
. Since the other two angles are 4 and 4, which are two times of 2, we can say the other two angles are 72 degrees each.
Pythagorean theorem (a^2 + b^2 = c^2) where a = 11 and b = 5. a and b are your two known sides and c (which is your hypotenuse) is what you are looking for. do you understand?
