A line perpendicular to one of two parallel lines is perpendicular to the other. B. Two lines are perpendicular if they intersect to form congruent. Finally, if, when EF meets JK and CD, it makes the interior angles on the same side less than two right angles, then JK, CD are not parallel, and they will meet on that same side. That is Postulate 5. Some writers however have replaced Postulate 5 with the following, which they think is intuitively simpler: Two intersecting straight lines.

SOLUTION: In quadrilateral ABCD, AB is congruent to CD, AB is parallel to CD, and BF and DE are perpendicular to diagonal AC at points F and how to get CD=7 cm when we will drop two perpendicular lines from D to AB as point E and from C to AB as point F. So,we can see that EF = CD (as the line drawns were perpendicular) Now In triangleADE, We know AD=15 and DE=12 So we can easily find AE = 9 Similarly from triangleBCF, we will get BF = 9cm therefore,EF = AB -(AE+BF) = 25 - 18 =7cm ** CD 5 1 2 AB 3x 2 2x 5 2x 1 10 2 2x x 5 10 3x 5 2x 1 10 AB 5 4(10) 1 20 5 60 CD 5 3(10) 5 30 Wi 3x 5 1 2 (4x 1 20) Use x to find AB and CD**.

If m (AC = 100, nd mOBOD. 53 Exercise 4.1: Lines and Triangles. Question 1: In the given figure, AB is a mirror. PQ is the incident ray and QR, the reflected ray. If , find . Ans: We know that the angle of incidence = angle of reflection. Hence, let. Since, AQB is a straight line, we have

Draw another line segment, CD, parallel to AB. Solution Use a ruler to draw a line segment. Label its endpoints A and B. Place the edge of a right triangle along AB as shown. Place a ruler against the bottom edge of the triangle. Slide the triangle along the ruler. Draw along the perpendicular edge of the triangle to create a line parallel to AB It is give that the lines AB and CD are parallel and angles 1 and 2 are in the ratio 3: 2. Let. In the figure angle 1 and 2 are supplementary. So, 3x + 2x = 180 ⇒ 5x = 180 ⇒ x = 36 ∠ 1 = 36 × 3 = 108 ° and ∠ 2 = 36 × 2 = 72 ° Since, angle 1 and 5 and angle 2 and 6 are corresponding angles, so. Since, angles 1 and 3 and 2 and 4 are. Construct Parallel Lines - Explanation and Examples. Constructing a line parallel to a given line that goes through a given point involves knowing some facts about parallel lines and copying angles. To do this, we will need to construct a transversal. This is a line that crosses two parallel lines. Several pairs of equal angles are created.
