The longest side in the right-angled triangle is ------------------

(a)  

If the lengths of two sides in a triangle are 2 cm. and 7 cm.,

then----------<the length of the third side <---------

(a)  

If the length of the median drawn from a vertex of a triangle equals half the opposite side to this vertex in length, then----------------(type of the angle)

(a)  

If the measure of an angle in the isosceles triangle equals 60°, then the triangle is -----------

(a)  

In the opposite figure:

Triangle ABC is equilateral, then m (ACD) =

In Triangle ABC which is right-angled at B, if AC = 20 cm., then the length of the median of the triangle drawn from B equals

XYZ is a triangle in which: m (Z) = 70° and m (Y) = 60°, then YZ ----------XY

The lengths which can be lengths of sides of a triangle are ----------

The triangle in which the measures of two angles of it are 42° and 69° is -----------

In the opposite figure: m(<C)=2m (<A) and , BC = 6 cm.

, then AC =
