Answer:
less
Step-by-step explanation:
<u>Here</u><u>, </u><u> </u><u>we </u><u>have </u><u>given </u>
- One isosceles triangle that means the given triangle having two sides equal.
- The dimensions of the triangle are 21cm, 21 cm and 16 cm.
Consider the given triangle as ABC . In ΔABC, AD acts as a median. It means Angle ADB = 90°
<u>Therefore</u><u>, </u>
<u>By </u><u>using </u><u>Pythagoras </u><u>theorem</u><u>, </u>
- It states that the sum of the squares of base and perpendicular height is equal to the square of the hypotenuse.
<u>That </u><u>is</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values </u>
Hence, The required height of the given isosceles triangle is 13.6 cm.
[ Note :- you can also solve this problem by using Heron's Formula but it's too lengthy to solve that's why I have used simple method ]
