2.An equilateral triangle with equal
3. An isosceles triangle with equal side
4.6 cm and third side 6.5 cm

please type the correct answer this question is come to my exam

Answer 1

Answer:

Step-by-step explanation:

(i) XY = 6.4 cm, ZY = 7.7 cm and XZ = 5 cm Construction:  Step 1: Draw a line. Marked Y and Z on the line such that YZ 7.7 cm.  Step 2: With Y as centre drawn an arc of radius 6.4 cm above the line YZ. Step 3: With Z as centre, drwan an arc or radius 5 cm to intersect arc drawn in steps. Marked the point of intersection as X.  Step 4: Joined YX and ZX. Now XYZ is the required triangle. (ii) An equilateral triangle of side 7.5 cm Construction:  Step 1: Drawn a line. Marked X and Y on the line such that XY = 7.5 cm.  

Step 2: With X as centre, drawn an arc of radius 7,5 cm above the line XY.  

Step 3: With Y as centre, drawn an arc of radius 7.5 cm to intersect arc drawn in steps. Marked the point of intersection as Z.

Step 4: Joined XZ and YZ. Now XYZ in the required triangle.

(iii) An isosceles triangle with equal sides 4.6 cm and third side 6.5 cm Construction:

 Step 1: Drawn a line. Marked X and Y on the line such that XY = 6.5 cm. Step 2: With X as centre, drawn an arc of radius 4.6 cm above the line XY Step 3: with Y as centre, drawn an arc of radius 4.6 cm to intersect arc drawn in steps. Marked the point of intersection as Z.

Step 4: Joined XZ and YZ. Now XYZ is the required triangle.
