Question

. If two straight lines intersect each other in such a way that one of the
angles formed measures 90°, show that each of the remaining angles
measures 90°​

Answer 1

Answer:

both the lines interested at 90° (perpendicular) .

Step-by-step explanation:

two lines interest eachother make 4angle of 90°

so that

angle A + angleB + angle C + angle D = 180°

90° + 90° + 90° + 90° = 180°
