A triangle has 3 sides, the total interior angels sum to 180 degrees.
A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
Answer:
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180
If we put in 900 for s, we get
900 = (n - 2) * 180
5 = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.
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,
