I'm sorry, but I am unable to draw images. However, I can provide you with instructions on how to accurately draw triangle ABC and calculate the length of side MC.
To draw triangle ABC accurately, follow these steps:
1. Start by drawing a straight line segment AB of any desired length.
2. Use a protractor to draw an angle at point A, which will be the angle A.
3. Measure the length of side AC and mark point C accordingly.
4. Connect points B and C to complete the triangle ABC.
To calculate the length of side MC, you can use the Pythagorean theorem if triangle ABC is a right-angled triangle. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
If triangle ABC is not a right-angled triangle, you can use the Law of Cosines to calculate the length of side MC. The Law of Cosines states that in any triangle, the square of one side is equal to the sum of the squares of the other two sides minus twice the product of the other two sides and the cosine of the included angle.
I hope this helps! Let me know if you need further assistance.

Materials:
- Ruler
- Protractor
- Compass
- Pencil
Steps:
1. Construct Triangle ABC:
- Draw a line segment AB.
- Using the protractor, mark an angle of 45° at point A.
- Using the compass, draw an arc with radius AB from point A that intersects the angle bisector of ∠BAC. This point is point C.
- Complete the triangle by connecting points B and C.
2. Measure Line Segment MC:
- Using the ruler, measure the length of line segment MC.
3. Calculate MC:
- Since triangle AMC is a right triangle (∠AMC = 90°), we can use the Pythagorean theorem to calculate MC:
- MC² = AM² + AC²
- AM = AB/2 (since triangle AMC is half of triangle ABC)
- AM = 1/2 - 5 cm = 2.5 cm
- From the trigonometry of triangle ABC, we know that AC = 5 cm.
- Substituting these values, we get:
- MC² = (2.5 cm)² + (5 cm)²
- MC² = 6.25 cm² + 25 cm²
- MC² = 31.25 cm²
- MC = √31.25 cm²
- MC ≈ 5.6 cm
Therefore, the length of MC is approximately 5.6 cm.
