Construct an angle of 90 degree at the initial point of a given ray and justify the construction |
| Answer» Given: A ray OA.Required: To construct an angle of 90° at O and justify the construction.Steps of Construction:1.\xa0Taking O as centre and some radius, draw an arc of a circle, which intersects OA, say at a point B.2.\xa0Taking B as centre and with the same radius as before, draw an are intersecting the previously drawn are, say at a point C.3.\xa0Taking C as centre and with the same radius as before, draw an arc intersecting the arc drawn in step 1, say at D.4.\xa0Draw the ray OE passing through C. Then ∠EOA = 60°.5.\xa0Draw the ray OF passing through D. Then ∠FOE = 60°.6. Next, taking C and D as centres and with the radius more than\xa0\xa0ID, draw arcs to intersect each other, say at G.7. Draw the ray OG. This ray OG is the bisector of the angle ∠FOE, i.e., ∠FOG\xa0Justification:(i) Join BC.Then. OC = OB = BC (By construction)∴ ∆COB is an equilateral triangle.∴ ∠COB = 60°.∴ ∠EOA = 60°.(ii) Join CD.Then, OD = OC = CD (By construction)∴ ∆DOC is an equilateral triangle. | |

Pi is an which number |
|
Answer» Irrational number irrational number\xa0Pi is a name given to the ratio of the circumference of a circle to the diameter. That means, for any circle, you can divide the circumference (the distance around the circle) by the diameter and always get exactly the same number. It doesn\'t matter how big or small the circle is, Pi remains the same. Pi is often written using the symbol\xa0\xa0and is pronounced "pie", just like the dessert.Pi was irrational, that is, that it can\'t be written as a ratio of integer numbers.Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way. |

Construct a triangle ABCin which BC=7cm, angle B=75 and AB+AC=13cm |
|
Answer» Thc Given : Base BC = 7cm, angle B = 75° and sum of two sides AB + AC = 13\xa0cm.Required : To Construct ∆ABCSTEPS OF CONSTRUCTION :1. Draw a ray BX and cut off a line segment BC = 7cm; from it.2. At B; construct angle YBX = 75°3. With B as centre and radius = 13\xa0cm (because AB + AC = 13cm) draw an arc to meet BY at D.4. Join CD5. Draw Perpendicular bisector PQ of CD intersecting BD at A.6. Join ACThen ABC is the required triangle.A lies on perpendicular bisector of CD.Therefore, AC = AD=> AB = BD - AD=> AB = BD - AC=> AB + AC = BD = 13cm\xa0 |

What is supplement andcomplement |
|
Answer» Supplement means 180°Complement means 90° Supplement is 180 Complement is 90 Complement angle is 90°. Supplement angle is180° Complementary Angles:Two angles are called complementary angles, if their sum is one right angle i.e. 90°.Each angle is called the complement of the other.\xa0Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.Clearly, 20° is the complement of 70° and 70° is the complement of 20°.Supplementary Angles:Two angles are called supplementary angles, if their sum is two right angles i.e. 180°.Each angle is called the supplement of the other.\xa0Example, 30° and 150° are supplementary angles, because 30° + 150° = 180°.Clearly, 30° is the supplement of 150° and 150° is the supplement of 30°.\xa0 |
