Draw a right triangle with side lengths of 3, 4, and 5 units (cm or inches - your choice). Make sure to label
all parts including side lengths, vertices, and the right angle. You may insert an actual picture of your
drawing below or upload the picture in the Unit 2 TGA submission area. Your drawing must be uniquely
created by you. PLEASE explain !!

Angle LIS is congruent to angle DIE making both of them 61°, angle LID and angle SIE are congruent as well. When you add LIS, DIE, LID, and SIE all add to 360°. So 61+61 equals 122. 360-122 is 238. You divide 238 by 2 to get 119. That will be the measure of angle SIE. A triangle is a total of 180° so add up the angles 27° + 119° to get 146°. Subtract that from 180° to get 34°.

34° is the measure of ISE

Hope this helps!
