Regular polygons with same number of sides are always

All equilateral triangles are similar because

All isosceles triangles are

Two polygons with the same number of sides are.................. If their corresponding angles are equal and corresponding sides are equal

If a line drawn parallel to one side of a triangle,then it divides other two sides in

If a line divides two sides of a triangle in the same ratio then the line is.......to the third side

The relation similarity is ........relation

In ∆ABC if DE ll BC then ∆ADE and ∆ABC are

If ∆ABC~∆DEF,LA=50⁰,LF=70⁰, then LB=

If ∆ABC ~∆DEF,a scale factor of 2/3 and DE=9cm then AB=

If in ∆XYZ,PQ ll YZ and XP:XY=3:5 and XQ=6cm then QZ=

In ∆PQR if XY ll QR then PX:PQ=

If in ∆ABC, if AD:DB=AE:EC,then

A person 1.65m tall casts 1.8m shadow,at the same time,a lamp post casts a shadow of 5.4 then height of lamp post is

In a quadrilateral ABCD if the diagonals are intersecting at 'O' such that AO/BO=CO/DO,then ABCD is a

If the ratio of the corresponding sides of two similar triangles is 3:2 then the ratio of their perimeters is

In ∆ABC,if DE||BC and AD:DB =2:3 then Ar[∆AFE]:Ar[∆ABC]=

Pythagoras theorem was earlier stated by the Indian mathematician is

If the corresponding sides of two similar triangles are equal,and the area of one triangle is 64 cm2, then the area of other triangle is

In a right triangle ABC LB= 90⁰ and BD is perpendicular to AC then ∆ADB~

In ∆ABC,LB=90⁰ then AB²+BC² , this is=AC²

1. In ΔABC, D and E are points on sides AB and AC respectively such that DE|| BC and AD : DB = 3 : 1. If EA = 3.3cm, then AC=_______

ΔABC and ΔPQR are similar triangles such that ∠A = 32° and ∠R = 65°, then ∠B is :

E and F are points on the sides PQ and PR

respectively of a Δ PQR. If PE = 4 cm, QE = 4.5 cm, PF = 8 cm and RF = 9 cm, then EF || QR.
