angle, can be measured using a protractor. although based on the right angle, we are able to differentiate between acute, obtuse or reflex angles. but if we have two acute angles to measure, then we cannot determine the greater angle among the two. therefore, we have to use a protractor...
Make a sun rod. 2. It should be as straight as possible and one meter long. Then take it to a level place that receives good sunlight. Drive your rod into the earth so that it forms a 90 degree angle (L-shape) with the ground. This is the first step to identify directions. ...
Determine the measurement of your angle in degrees. For example, suppose you have a 90-degree angle. Step 2 Convert from degrees to radians by multiplying the number of degrees by pi/180. For a 90-degree angle, multiply 90 by pi/180 to get pi/2. Or, if you had an angle of 270 d...
How to determine the midpoint of each line segment with the given endpoints A shape is constructed from four right angled isosceles triangles. Find the area of the shape if the length of one of the diagonals measures 12 cm. A right-angled triangular flag is made for the premiers of a sch...
Determine the type of triangle that includes the angle you are trying to find. This can be an equilateral triangle, which has three equal angles to go with its three equal sides; an isosceles triangle, which has two equal sides and two equal angles; a right triangle, which has a 90-deg...
To determine what kind of parallelogram you're looking at, ask yourself if it has all 90-degree angles. If yes, it's either a square or a rectangle. A rectangle has two sides that are slightly longer than the others, whereas a square has sides of all equal length. Either way, you ...
We begin taking an in-depth look at geometry by first considering parallelism and perpendicularity in a two-dimensional (planar) setting. As it turns out, how we define these concepts will determine the characteristics of the various figures that we will
Push the whole needle straight down into your skin in one quick smooth motion at a 90-degree angle (straight up and down). If you are thin, you may find it better to insert the needle at a 45-degree angle. Be sure to hold the skin fold as you give the shot. This will help make...
A = (Sector Angle / 360) * (π * r^2) Using the example from slide No. 5, the radius is 4.5 inches, and the sector angle is 34 degree, you would have: A = 34 / 360 * (3.14 * 4.5^2) A = .094 * (63.585) Rounding to the nearest tenth yields: ...
