Answer:
(-3, 3)
Step-by-step explanation:
The equation of line AB is
Since the y-intercept of the given line is (0,2), the line AB and the given line intersect at (0,2).
By definition, (0,2) is the midpoint of AA', where A' is the image of A after the reflection.
So, the coordinates of A' are (-3, 3)
Answer:
hi
x+102° =180°[ Being cointerior angle]
x=180°-102°
x=78°
Also,
y=102°[ the opposite angle of parallelogram are equal]
z=78°[ the opposite of parallelogram are equal]
Hence, x=78°,y=102° and z=78°
To use the AA postulate directly, you need to show that two corresponding angles are congruent. In order to show that here, you must calculate the value of one of the missing angle measures. Either of the missing angles can be found by invoking the fact that the sum of angles in a triangle is 180°.
After finding either missing angle, you can show that the measures of two angles in one triangle are identical to the measures of two angles in the other triangle, hence the triangles are similar by the AA postulate.
