Q. 1. In the figure, if AB∥ CD,CD∥EF and y : z = 3 : 7. Find x.
Q 2. In the figure, if AB∥CD,EF⊥CD and angle GED=126 degree. Find angle AGE, angle GEF and angle FGE.
Q 3. In the figure, if PQ∥ST, angle PQR = 110 degree and angle RST = 130 degree, Find angle QRS.
[Hint: Draw a line parallel to ST through point R]
Q 4. In the figure, if AB∥CD, angle APQ = 50 degree and angle PRD = 127 degree, Find x and y.
Q 5. In the figure, PQ and RS are two mirrors placed parallel to each other. An incident ray AB strikes the mirror PQ at B, the reflected ray moves along the path BC and strikes the mirror RS at C and again reflects back along CD. Prove that AB∥CD.
