Construct a right triangle when one side is 3.5 cm and the sum of its other side and hypotenuse is 5.5 cm
Answers
Construction of right triangle when one side and sum of hypotenuse and the other side is given:
- Draw a line segment AB = 3.5 cm.
- Draw a ray AX from A at 90°.
- Draw an arc on AX with a radius of 5.5 cm.
- Mark this point as C.
- Join BC.
- Measure ACB and draw a ray BY from B such that ∠ACB = ∠CBY and BY passes through AC.
- Mark the point where ray BY meets AC as D.
- ABD is the required triangle.
Sorry friends no geometry tool.
steps of construction:
* Draw a line BC=5.5cm.(base)
*From B, an angle on 90°,Angle XBC
*Cut off BD=5.5cm
*join C to D, CD
*Draw perpendicular bisector AE of line CD, By starting with two points C & D as centres, Draw two arcs on both sides( up & down) with radius approxly a bit more than half of CD.
*The place where this AE bisector intersects BD mark it point A.
*Join A to C, AC.
verification
on measuring by ruler (AB +AC)=5.5cm
Justification
AD=AC .......(1)
(Lies on the same perpendicular bisector AE)
Now: BX=AB+AD=5.5
by equation (1)
BX=AB + AC=5.5
OR
AB+AB=5.5cm
Or
the sum of hypotenuse & one side is 5.5cm,Hence our construction is finished
