Triangles and pythagorean theorem

What is a transversal line?

• two angles with the same measure

• two angles whose sum is 180

• A line that intersects two or more lines

• good question

what is the equation to find the pythagorean theorem

• a²+b²=c²

• a+b²=c

what does a formal proof contain?

• statements and reasons organized in two columns

• definitions

• the same measure

find the value of x in the triangle if the other measures are a right angle and 60

• x=30

• 90+60=150

• 150+30=180

• 30 degrees squared

find the sum of the interior angles of a nonagon

• 9-2(180)

• 1260/9

• 7(180)=1260

What is the distance formula?

• a²+b²=c²

• (X2-X1)²+(Y2-Y1)²
