A compass is a tool used to draw arcs and circles. Even though a compass draws curves, we can use one to draw an angle. In this lesson, we will use a compass and a straight edge to draw a copy of an angle. Making a Copy
Straightedge and compass constructions, algebraically speaking, enable one to construct points on the plane whose coordinates are a result of some combination of addition, subtraction, multiplication, division, and square root operator. This I won't go into detail; it is not difficult to figure ou...
Given three points, it is always possible to draw a circle that passes through all three. This page shows how to construct (draw) a circle through 3 given points with compass and straightedge or ruler. It works by joining two pairs of points to create
How to Construct an Angle Bisector To construct an angle bisector for angle ∠A formed by vertex A and two lines AB and AC, follow the steps below. Step 1: Set the length of a compass to about a half of AB drawn on the paper. Place the needle point of a compass on vertex A an...
Let JK be the median of LMBA. Find \angle ALM. How to construct an acute triangle with a compass In the figure below, triangle \triangle KVL is an isosceles triangle with KV = LV , the MP segment is a median of triangle \triangle MKL and passes through the point V . Show that for...
Construction of 30 Degrees Using Compass An angle of 30 degrees can also be constructed using a compass. Now let us see how to construct a 30-degree angle using a compass, ruler, and a pencil. Follow the steps given below: Draw a ray AB. With A as the center and a suitableradiuson...
Step 1:Construct a line segmentAB=4cm. Step 2:Construct a 60-degree angle at pointA. Step 3:Construct a line segmentAD=5cmon the other arm of the angle. Step 4:Then, place the sharp point of5cmaboveB Step 5:Stretch your compasses to4cm, place the sharp end at D and draw anarcto...

Constructing triangles involves the use of a compass and a straight edge to create three-sided shapes. Explore types of geometric construction, triangle construction, congruent triangles, models with two sides and an angle or two angles and one side, and equilateral triangles. Related...
To construct a good map, the captured images need to cover the same areas from different angles. When localizing against a map, the map should contain data from a captured image with a similar viewpoint in it. The captured images don't need to be identical by any means, but should have...
