Answer: 
Step-by-step explanation:
Since, By the given diagram,
In quadrilateral ABCD, all angles are right angles ⇒ DC = AB = 15 cm and CB = DA
Also, In triangle DFA,
⇒ 
⇒ 
⇒ 
Now, In triangle, DEC,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Answer:
AAS, the two equal angles, the two right triangles, and the shared side
Step-by-step explanation:
Answer:
6.04 inches.
Step-by-step explanation:
Corbin want's to make a model, in which every 100 feet would be shown by 1 inch.
The monument is 604 feet in height.
Divide 604 with 100:
604/100 = 6.04
The height of Corbin's model would thereby be 6.04 inches.

Step-by-step explanation:
Given :
Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles
To find : by which property are angles 4 and 5 congruent
Solution :
We know that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
Also, we know that if two things are equal to the same thing then they are equal to each other . In this case, we can say that if two angles are congruent to a third angle, then they are congruent to each other. As angles 4 and 5 are both congruent to angle 1, they are congruent to each other but angles 4 and 5 are alternate interior angles. So, if parallel lines have a transversal, alternate interior angles are congruent.
