Answer: size and shape

Step-by-step explanation:

Hi, triangles are congruent if they have the same size and shape. It means that they have exactly the same three sides, and exactly the same three angles, but one may be a mirror image of the other.

Each part of the triangle (side or angle) is congruent to the corresponding part in the other triangle.

Feel free to ask for more if needed or if you did not understand something.

What is an equation of the line that passes through the points (4,-6) and (8,-4)​
qaws [65]

Answer:

y =  \frac{1}{2} x - 8

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient (also known as slope) and c is the y-intercept (the point through which the line cuts through the y-axis).

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

Using the gradient formula above,

m =  \frac{ -4 - ( - 6)}{8 - 4}  \\ m =  \frac{ - 4 + 6}{4}  \\ m =  \frac{2}{4}  \\ m =  \frac{1}{2}

Substitute the value of m into the equation:

y= ½x +c

To find the value of c, substitute a pair of coordinates.

When x=4, y= -6,

-6= ½(4) +c

-6= 2 +c

c= -6 -2 <em>(</em><em>-2</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

c= -8 <em>(</em><em>simplify</em><em>)</em>

Thus, the equation of the line is y= ½x -8.
