It is given that `triangle DEF ~ triangle RPQ`. Is it true to say that `angle D = angle R` and `angle F = angle P`?Why?

It is given that DeltaDEF~DeltaRPQ . Is it true to say that angleD = angleR and angleF= angleP ? Why?

It is given that Delta ABC cong Delta RPQ .Is it true to say that BC =QR ? Why ?

In the given figure, if angleD = angleC, then it is true that triangle ADE ~ triangle ACB? Why?

Right triangle a triangle whose one angle is a right angle is called a right-angled triangle or a right triangle.

Show that if sum of the two angles of a triangle is equal to the third angle then the triangle is right angled triangle.

In Delta PQR , If angle R gt angle Q, then

In a triangle PQR , angle P = 110^(@) , PQ = PR . Find angle Q and angle R

Is it true to say that, if in two triangles, an angle of one triangle is equal to an angle of another triangle and two sides of one triangle are proportional to the two sides of the other triangle, then the triangles are similar? Give reason for your answer.
