The term “coordinate” represents the position of the point along the line, arc and so on, whereas the term “ordinate” represents the value of a coordinate on the y-axis.

Aryan Sharma 3 years, 6 months ago

Here, we need to draw a line AB parallel to line PQ, through point M as shown in Fig. 6.25. Now, AB || PQ and PQ || RS Therefore, AB || RS (Why?) Now, ∠ QXM + ∠ XMB = 180° (AB || PQ, Interior angles on the same side of the transversal XM) But ∠ QXM = 135° So, 135° + ∠ XMB = 180° Therefore, ∠ XMB = 45° (1) Now, ∠ BMY = ∠ MYR (AB || RS, Alternate angles) Therefore, ∠ BMY = 40° (2) Adding (1) and (2), you get ∠ XMB + ∠ BMY = 45° + 40° That is, ∠ XMY = 85°

Given that ABCD is a square. To prove : AC=BD and AC and BD bisect each other at right angles. Proof: (i) In a ΔABC and ΔBAD, AB=AB ( common line) BC=AD ( opppsite sides of a square) ∠ABC=∠BAD ( = 90° ) ΔABC≅ΔBAD( By SAS property) AC=BD ( by CPCT). (ii) In a ΔOAD and ΔOCB, AD=CB ( opposite sides of a square) ∠OAD=∠OCB ( transversal AC ) ∠ODA=∠OBC ( transversal BD ) ΔOAD≅ΔOCB (ASA property) OA=OC ---------(i) Similarly OB=OD ----------(ii) From (i) and (ii) AC and BD bisect each other. Now in a ΔOBA and ΔODA, OB=OD ( from (ii) ) BA=DA OA=OA ( common line ) ΔAOB=ΔAOD----(iii) ( by CPCT ∠AOB+∠AOD=180° (linear pair) 2∠AOB=180° ∠AOB=∠AOD=90° ∴AC and BD bisect each other at right angles.

Thank you ?

Amanjot Kaur 3 years, 7 months ago

We have a straight line AB. Take a point P not on AB, but some distance away. We draw PC the perpendicular on to AB meeting AB at C. We draw another line from P to D, where D lies on AB. We show that PD > PC, for any point D other than C. In the triangle PCD, use the Pythagorean law for sides: PC² + CD² = DP² Since CD² is positive and adds to PC², PC²+CD² > PC² Hence DP² > PC² So DP > PC SO PC, the perpendicular distance from an external point to a line segment, is the shortest.
