Measure each of the angles in each triangle using a protractor. Extend the sides if necessary. Make sure that the measures of the three angles add up to 180°. Record your answers in the Triangle Classification Table. Once you have figured out the measurement of each angle in the triangle, classify the triangle as acute, obtuse, or right. 1. 2 ... others have only three. The degree of magnification for each objective lens is indicated on its side. Let’s take a look at each progressing from the shortest to longest objective lenses, being sure to rotate the revolving nosepiece to click each objective lens into position above the stage before examining it:

the first exercise, though, we will review how to solve for a missing side using trigonometry. Exercise #1: Find the length of AB to the nearest tenth . Solving for a Missing Angle – The process for finding a missing angle in a right triangle is very similar Parts of a degree are now usually referred to decimally. For instance seven and a half degrees is now usually written 7.5°. When a single angle is drawn on a xy-plane for analysis, we’ll draw it in standard position with the vertex at the origin (0,0), one side of the angle along the x-axis, and the other side above the x-axis. You would think that measuring the square footage of your home would be pretty straight forward - get out the tape measure, break the home up into rectangles, and add up the area of the rectangles. Find the measure of each side indicated. Round to the nearest tenth. 15) 12 x A B C 37° 16) 12 x AB C 18° Find the measure of each angle indicated. Round to the nearest tenth. 17) 7 B4.9 A C q 18) 12 6A B C q State the quadrant in which the terminal side of each angle lies. 19) 11p 6 20) -43p 18 Find the reference angle. 21) 5p 9 22) -550° Find the measure of each angle indicated. Round to the nearest tenth. 1) ~ 2) 13 0 B Date Period ID: 1 3) c 4) 8 5 0 B A 5) c 6) 7) 9) 13 11 B A B C2.4A B "A C 16 C A B 7 C C 6 A 10) 15 16 C 11) 13 B 5 C 12) A ~ 9,4 B 6 C Jun 14, 2016 · Make sure you select the correct base and height lengths for each rectangle. Step 4. All you need to do now is to add up the 2 answers from step 3. 20 + 28 = 48 cm². So the total area of the compound shape is 48 cm². Summary: Find the missing lengths around your L shape and divide the shape into 2 rectangles.

Draw the point of intersection between circle B and segment AB. Draw a circle with the center A and a radius equal to CB. Draw point E and create a ray from point B through point E. Find all the possible outcomes of flipping a coin (heads or tails) FOUR times. Side AB corresponds to Side DE, Side AC corresponds to Side DF, and Side BC corresponds to side EF. If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. Let's find the length of side DF, labeled x. We can write a proportion, like this:

congruent. Without calculating, determine if the measure of the fourth angle in each of the following situations is greater than, less than, or equal to 90°. Explain your reasoning. See margin. a. The three congruent angles each measure 89°. b. The three congruent angles each measure 90°. c. The three congruent angles each measure 91°.
