if angle a and b are linear pair and a:b=2:3, then the measure of angle a and b are |
|
Answer» First we can take the ratio 2:3 as 2y and 3y , It is a linear pair so angle a + angle b=180° 2y+3y=180° 5y=180° y=180°/5 y= 36°Hence y=36°, 2y=2(36)= 72° 3y=3(36)=108°Hence the angles are 72°and 108°. Let the angle a be 2x and b be 3xSum of linear pair =180°a+b=180°2x+3x=180°5x=180°x=180°/5x=36°The measure of a and b are 2×36° and 3×36°72° and 108°. |

Properties of isosceles triangle |
|
Answer» I will Provide You Very Best Solution It is The Triangle have Two same side and one different side is called Isosceles Triangle ? Each geometric figure has some properties that make it different and unique from the others. Here is a list of a few properties of isosceles triangles:The two equal sides of an isosceles triangle are called the\xa0legs\xa0and the angle between them is called the\xa0vertex angle\xa0or apex angle.The side opposite the vertex angle is called the base and base angles are equal.The perpendicular\xa0from the vertex angle bisects the base\xa0and the vertex angle. The triangle which have two sides equal and one side and unequal is called an isosceles triangle Simple two sides and Angles are equal in an isosceles triangle? |

Prove triangle=180° |
|
Answer» Let the sides of triangle be x As we know triangle have 3 sidesHence, sides of triangle be=3xSum of three sides of triangle=180°So,3x=180°x=180/3x=60°Hence each side of triangle is 60+60+60Which is 180Hence proved..... Sum of three angles is 180 degree If you understand with this answer like please TrianglePQR with angle <1,<2and <3.Then<1+<2+<3=180 degree<1+<4+<5=180 degree(linear pair).<1+<2+<3=180degree(from(1)and (2) |
