Answer:
Step-by-step explanation:
Given:
bisects angle BAC
Triangle ABC is isosceles triangle, because 
Angles adjacent to the base of isosceles triangle ABC are congruent.
Hence,
The sum of the measures of all interior angles is 180°, so,
Since bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,
AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,
Answer:
Step-by-step explanation: The second book has 346 pages, the 3rd book has 264 pages. Together they have a total of 346+264 = 610 pages. To find how many pages less is book one than two and 3 combined subtract 137 from the total for books 2 and 3 (610 - 137 = 473). Book 1 is 473 pages less than the other 2 books.

Answer:
statement D is correct.
<em>Statement: ∠7 ≅ ∠6 and ∠8 ≅ ∠5</em>
<em>Reason: Vertical Angles Theorem</em>
Step-by-step explanation:
Given that
3 ≅ ∠7 and ∠4 ≅ ∠8
from statement 2 because they are corresponding angles.
∠8 ≅ ∠5
because its vertical angles
The vertical angles theorem is about angles that are opposite each other.
So,
∠4 ≅ ∠8 and ∠8 ≅ ∠5
which means
<h3> ∠4 ≅ ∠5 </h3>
Hence,
∠3 = ∠7
∠4 = ∠5
they are known as interior alternative angles.
