Draw a right angled triangle with length 4cm and 3cm construct a similar triangle with a scale factor 5by3
Answers
Answer:
Step-by-step explanation:Lets first draw a rough diagram Let ABC be the isosceles triangle with
AB = AC
Base = BC = 4 cm
Altitude = 3 cm
we need to draw Δ ABC
In isosceles triangle , median and altitude are same
So, AD is the median and altitude
AD is the perpendicular bisector of BC
Steps of construction
1 . draw base BC of side 4 cm
2. Draw perpendicular bisector of BC.
3. let perpendicular bisector intersect BC at point D.
4. Taking point D as centre , Take 3 cm as radius.
5. Join AB and AC
ABC is the required triangle
Now we have to make 5/3 times its size
Steps of construction of new triangle
1. Draw any ray BX making an Acute angle with BC on the side opposite to the vertex A
2. Mark 5 points B,B₁, B₂, B₃,B₄, B₅ on BX so that all are equal.
3. Join B₃C and draw a line through B₅ parallel to B₃C
4. Draw a line through c' parallel to the line AC to intersect AB extended at A'
∴ Required Δ A'BC'
