Construct triangle ABC in which/AB/=7cm,/AC/=9.5cm and B line A,C=120 degree.Measure /BC/

To construct triangle ABC, we'll need to follow these steps:


Step 1: Draw a line segment AB of length 7 cm.
Step 2: Using a compass, place the point of the compass at point A and draw an arc with a radius of 9.5 cm. This arc will intersect line segment AB.
Step 3: From the intersection point on line AB, draw a line segment AC of length 9.5 cm. This will complete the construction of triangle ABC, where /AB/ = 7 cm, and /AC/ = 9.5 cm.

To measure the length of /BC/ in this constructed triangle, follow these steps:

Step 4: Using a ruler, measure the length of line segment BC. Place one end of the ruler on point B and extend the ruler until it reaches point C.
Step 5: Observe the measurement on the ruler, and that will give you the length of line segment BC.

By following these steps, you can construct triangle ABC and measure the length of /BC/.

To construct triangle ABC with AB = 7cm, AC = 9.5cm, and ∠BAC = 120°, follow these steps:

Step 1: Draw a line segment AB of 7cm.
Step 2: At point A, draw a ray in any direction.
Step 3: Using a compass, put the needle on point A and draw an arc with a radius of 9.5cm to intersect the ray. Label this point C.
Step 4: With the same compass setting, put the needle on point C and draw an arc to intersect the line segment AB. Label this point B.
Step 5: Draw a straight line from point B to point C.
Step 6: Measure the length of BC using a ruler or measuring tape.

Following these steps will allow you to construct triangle ABC and measure the length of BC.
