The circumcenter of a triangle is the center of a circle who's radius touches all three of the triangle's vertices. The circumcenter can be found using the intersection of 2 or more perpendicular bisectors. A bisector is a line perpendicular from the mid point of a triangle's line segment.To find the circumcenter of a triangle, create two bisectors by following these steps:StepsWith a compass, draw a circle from the first point in the triangle larger then the triangle.Draw the same size circle from point two.Draw the same size circle from point three.Draw a line from the two intersecting points of circle one and two.Draw a line from the two intersecting points of circle two and three.The intersection of the lines from step 4 and 5 will define the circumcenter of the triangle.
Area for any triangle is 1/2 base x height. If you don't know the height (must be perpendicular to the base) then there are trig formulas depending on what is known. Heron's formula is based on knowing the 3 sides (works for any triangle). Step 1 find the semiperimeter, s. s = (a+b+c)/2 Step 2 find the area. A = sq root [s(s-a)(s-b)(s-c)] If you only know 2 sides and an angle there are other formulas as well.
The step to verify an isosceles triangle is: 1) Find the intersection points of the lines. 2) Find the distance for each intersection points. 3) If 2 of the distance are the same then it is an isosceles triangle.
23.2. Step 1: 5.8*8=46.4 Step 2: 46.4 ÷ 2=23.2 So that is your answer.
First find the area of the top triangle. Multiply that by 2. Then, find the the area of one of the side triangles. Multiply that by 3. Add both numbers and remember to but a 2 on the upper left of the total.

If the compass angle is changed, the entire geometric shape being drawn is different. For example, if a triangle is being drawn, it could change from an obtuse triangle from a ninety degree triangle.

Example 1: A right triangle has one other angle that is 35º. What is the size of the third angle? Solution: Step 1:A right triangle has one angle = 90°. Sum of known angles is 90° + 35º = 125°. Step 2:The sum of all the angles in any triangle is 180º. Subtract sum of known angles from 180°. 180° - 125° = 55° Answer:The size of the third angle is 55°

If you know the length of the sides of a triangle you can find all the angles of the triangle using the Law of cosines such as: Step 1. cos A = (b^2 + c^2 - a^2)/(2bc) cos B = (a^2 + c^2 - b^2)/(2ac) cos C = (a^2 + b^2 - c^2)/(2ab) Step 2. Find the arc cosine A, arc cosine B, and arc cosine C in order to find the angles A, B, and C.
The first step when inscribing a square quadrilateral triangle or a hexagon in a circle is to connect the endpoints of the diameters to form a square.
equilateral triangle ;)
There is an obtuse angle at either end of the bay window in our living room. A lot of the corners of the rooms of our house are not actually as square as they should be and are in fact slightly obtuse (eg 91o or 92o). At the top of some of our walls (at the join with the ceiling) there is a piece of caving which means the angle there is obtuse. To make full use of the land next to our house, our garage is shaped like a trapezium (the front is about 1m shorter than the back) so there is an obtuse angle between the front and one side of our garage. We have a floor standing lamp with an uplighting shade that makes an obtuse angle (with the upright pole). There are some obtuse angles in the mitring in the corners (of the covers) of the trunking I've put in. There are obtuse angles under the mantelpiece above our fireplace. The corner of one of the worktops in our kitchen has had the corner cut off, leaving two obtuse angles. Our staircase goes round a corner and the step that starts the corner has an obtuse angls . When any door is opened (unless it is at a right angle) it forms an obtuse angle (with either the doorway or the wall).
