construct ∆ABC in which AB=4cm,BC=7cm and CA=3cm. Which type of triangle is this? please answer this question with a pic i have tried this many times but im not able to get it please help i need the steps of the construction too
Answers
2.with A as centre and radius equal to 4cm draw an arc
3.with C as centre and radius equal to 7cm draw another arc intersecting previous arc at B.
4. Join AB and BC
Thus triangle ABC is the required triangle.
It is a scalene triangle
Answer:
Step 1: Sketch a crude triangle and name it with the necessary dimensions.
Step 2: Draw a 4 cm-long line segment AB.
Step 3: Draw an arc with a 3 cm radius with A at its center.
Step 4: Draw a second arc of 7 cm in radius with B as its center, intersecting the previous arc at C.
Step 5: Join C, A, and C, B. The necessary ABC is built. Such a triangle is a triangle with an obtuse angle.
Step-by-step explanation:
Geometric Construction
Lines, angles, object forms, sizes, and measurements are all aspects of the idea of geometry. Using tools like rulers, protractors, and compasses, we must precisely draw shapes to represent them on paper. A line's structure is the most basic. To draw a line, we begin with a point and steadily expand it. A line may be finitely long or have a fixed length. Similar to how rectangles and circles may be built using the right method and the specified dimensions.
Geometric construction is the practice of drawing exact lines, line segments, shapes, circles, and other objects using a ruler, compass, or protractor.
Drawing a line segment, parallel and perpendicular lines, circles, perpendicular bisectors, and even tangents to circles are required for the majority of geometrical shapes.
Given,
AB = f = 4 cm
BC = i = 7 cm
CA = h = 3 c m
