How do you construct a triangle given its base a base angle and difference of other two sides?
To construct a triangle, given its base, a base angle and the difference of other two sides
- Obtain the base, base angle and the sum of the other two sides.
- Draw the base BC.
- Draw ∠XBC of measure equal to that of ∠ABC.
- From ray BX, the cut-off line segment BD equal to the difference of the other two sides (AB – AC).
Can you construct a triangle whose perimeter is 12cm and the ratio of its sides is 1 ratio 2 ratio 3?
Hence, ΔABC is the required triangle whose sides are in the ratio 1 : 2 : 3 and having perimeter 12 cm.
How do you construct a triangle given the perimeter and altitude?
Procedure: Draw a line AB equal to half the perimeter. From B erect a perpendicular and make BC equal to the altitude. Join A to C and bisect AC. Locate D and make DB= BE and complete triangle.
How do you justify the construction of a triangle?
Justification of Construction: We can justify the construction by showing ABC as an equilateral triangle i.e., AB = BC = AC = 5 cm and ∠A = ∠B = ∠C = 60°. In ΔABC, we have AC = AB = 5 cm and ∠A = 60°. From equations (1) and (2), ΔABC is an equilateral triangle.
How do you construct a triangle given two sides?
diagram
- Draw the base BC and at the point B make an angle, say XBC equal to the given angle.
- Cut a line segment BD equal to AB + AC from the ray BX.
- Join DC and make an angle DCY equal to BDC.
- Let CY intersect BX at A.
How do you construct a triangle given the perimeter?
Steps of Construction: Step 1: Draw a line segment XY such that XY = AB + BC + CA (i.e. perimeter of triangle ABC) and draw the angle lines at X and Y such that ∠LXY = ∠B and ∠MYX = ∠C. Step 2: Draw the angle bisectors of ∠LXY and ∠MYX and let them meet at A.
How do you construct a triangle given its perimeter and its two base angles?
The steps of construction are:
- Draw a line segment XY of length equal to AB + AC + BC, that is, 15 cm.
- From point X, using the protractor construct ∠LXY which is equal to ∠B, that is, 55°.
- From the point Y, construct ∠MYX which is equal to ∠C, that is, 60°.
- Using the compass, construct the bisectors of ∠LXY and ∠MYX.
How do you construct a right triangle whose base is 12cm and sum of its hypotenuse and other side is 18cm?
Steps Of Construction:
- Draw a line segment AB = 12cm.
- Draw a ray AX making right angle with AB.
- Cut a line segment AD of length 18 cm from ray AX.
- Join BD and make an angle DBY equal to ADB.
- Let BY intersect AX at C. Join AC and BC.
- Triangle ABC is the required triangle.
