The perpendicular bisectors of two sides of a triangle meet at point that belongs to the third side. Prove that this is a right
devlian [24]
<h3>Step-by-step explanation:</h3>

The point of intersection of the perpendicular bisectors of a triangle is the circumcenter, the center of the circle that contains the three triangle vertices.

If that center is on one side, that side must be a diameter of the circle. The diameter cuts the circle into two arcs, each of which measures 180°.

The third vertex of the triangle and its two legs form an inscribed angle that subtends an arc of 180°. The measure of that angle is half the measure of the arc, so the angle measures 90° and is a <em>right angle</em>.

A triangle with a right angle is a right triangle. QED

Bob and Mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
Damm [24]
Not this riddle again


3 kids
what you are supposed to do is factor 72 and see their sums
1+1+72=74
1+2+36=39
1+3+24=28
1+4+18=23
2+2+18=22
1+6+12=19
2+3+12=17
1+8+9=18
2+4+9=15
2+6+6=14
3+3+8=14
3+4+6=13


notice that all the sums are different except for the 2 that add to 14
since there is not enough info, we can conclude that the sum was 14 and that the ages is either 2,6,6 or 3,3,8
after he says, "the youngest is called justice"
now we know there is a youngest
it cannot be 3,3,8 because 3 and 3 are both youngest
therefor the ages are
2,6 and 6 years old

PLEASE HELP(will mark brainiest) Draw a quadrilateral A'B'C'D' that is a translation (x + 2, y - 4) of quadrilateral ABCD.
yuradex [85]

Answer:

New coordinates:

A: (2,-4)

B: (6,-4)

C: (7,1)

D: (3,1)

Step-by-step explanation:

You translate each of the starting coordinates by adding or subtracting them by the coordinates given.  

x coordinates:  0+2=2              y coordinates:   0-4= -4

                         4+2=6                                         0-4= -4

                         5+2=7                                          5-4= 1

                         1+2=3                                           5-4= 1
