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

Answer:
Step-by-step explanation:
1 )  2 + 7t                        [ there are no like terms , so no further simplifying ] 
2) 6r + ( - 16 r )
    =  6 r - 16 r                 [ both are like terms ]
    = - 10 r
3) (3x + 2 ) + ( 2x - 4 )
    = 3x + 2 + 2x - 4
    = 3x + 2x - 4 + 2               [ arranging like terms together ]
    = 5x - 2
4) (8 n² - 3 n + 6 ) + ( n - 2 )
    = 8n² - 3n  + 6 + n - 2 
    = 8n² - 3n + n + 6 - 2             [ bringing like terms together ]
    = 8n² - 2n + 4
