Answer:
- all right angles are congruent.
- opposite sides of a parallelogram are congruent
- SAS congruence postulate
- corresponding parts of congruent triangles are congruent
Step-by-step explanation:
Given : Parallelogram JKLM is a rectangle and by the definition of rectangle, 
are right angles,
Since all interior angles of rectangle are right angle.
then 
, because all right angles are congruent.
Also, opposite sides of a parallelogram are congruent.
and 
by the reflexive property of congruence.
Now, by the SAS congruence postulate,
,
Since corresponding parts of congruent triangles are congruent, ∴
- The SAS postulate says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle then the two triangles are congruent.
Answer:
4y=123_2y=320
Step-by-step explanation:
Answer: y= -4x/3 - 4/3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=3x4−32.
The slope of the perpendicular line is negative inverse: m=−43.
So, the equation of the perpendicular line is y=−4x3+a.
To find a, we use the fact that the line should pass through the given point: −4=(−43)⋅(2)+a.
Thus, a=−43.
Therefore, the equation of the line is y=−4x3−43.
The solutions are C = 2 and C = -2
We can find this by solving for C.
C^2 - 4 = 0 ----> add 4 to both sides
C^2 = 4 ----> Take the square root of both sides
C = 2
However, since we used the square root function, we have to include a negative form of the answer as well as the positive one we found.
