Isosceles triangle PQR is shown in the diagram. Which statement about the medians of the triangle PQR is true?
A). The medians of triangle PQR are concurrent at a point and the medians of the congruent sides of triangle PQR are congruent.
B). Each median of PQR bisects each of the other medians and creates bisected angles angles at the vertices of PQR.
C). The medians of PQR connect to create four congruent isosceles triangles in the interior of PQR.
D). The medians of PQR are perpendicular to the side opposite the vertex, creating two congruent triangles.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.

multiply each one by 3.14

step-by-step explanation:

5.762159

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
