Question 1 In Fig. 2.23, list all the angles possible. Did you find them all? Now, guess the measures of all the angles. Then, measure the angles with a protractor. Record all your numbers in a table. See how close your guesses are to the actual measures. There are a lot of angles here For an angle, we need 1 vertex 2 arms from that vertex So, we take every corner point and make angles from there Now, instead of guessing every angle and measuring it We try with one angle - ∠ ACD Now, ∠ ACD seems acute angle, so less than 90° Let’s assume it is 65°. Now let’s find from Protractor Finding ∠ ACD from protractor Thus, ∠ ACD = 74° Now, can you try other angles and name the measurement in the comment below?
