Show that in a right angle triangle, the hypotenuse is the longest side |
|
Answer» Let ABC be a right triangle in which angle B=90°Then,angleA+angleC=90°.therefore,angleB>angleA and angleB>angleC=>AC>BC and AC>AB[side opp. to larger angle is longer].therefore,AC is the longest side.Hence,in a right triangle,the hypotenuse is the longest side. In triangle abc ac is perpendicular to ab. |

How we can prove that root 2 is not a rational number |
| Answer» Given √2 is irrational number.Let √2 = a / b wher a,b are integers b ≠ 0we also suppose that a / b is written in the simplest formNow √2 = a / b⇒ 2 = a2 / b2\xa0⇒ 2b2 = a2∴ 2b2 is divisible by 2⇒ a2 is divisible by 2 ⇒ a is divisible by 2 ∴ let a = 2ca2 = 4c2 ⇒ 2b2 = 4c2⇒\xa0b2 = 2c2∴ 2c2 is divisible by 2∴ b2\xa0 is divisible by 2∴ b is divisible by 2∴a are b are divisible by 2 .this contradicts our supposition that a/b is written in the simplest formHence our supposition is wrong∴ √2 is not rational number. | |

Construct a ∆ABC in which AB=6cm angle A=60° and AC-AB=2cm |
| Answer» Firstly draw a line segment AB of 6 cm. Contruct a angle of 60 on A to x. You can take any alphabaet instead of x. Then produce ax in reverse direction and draw an arc of 2 cm from A and take point d where arc intersect produced AX. Then join D to B and draw aperpendicular of DB join both arcs and produce which intersect AX at C then join B toC triangle ABC is required triagle | |
